An ignition system problem is one of the most common reasons for an engine to misfire. So lets say that I have a rotor phasing issue. Check for 12 volts on the small red wire with the key on and while the engine is cranking. An MSD must be connected directly to the positive battery terminal to ensure that its transformer and capacitor receive a direct 12 volt power supply. If it test out ok then it would be a good idea to run the grounds to the frame instead of the body. 29K 272. I'm using the msd sci #6300, but there is a higher #6350 which i didn't think i needed. This process should trigger the MSD sending a spark to the coil and out the coil wire. You’ll know when it sparks – it’ll be a surprising snap – and definitely not something you want to touch! I can use timing accessories along with an MSD 6A ignition. Yo! After checking all of the voltages and connections as listed above, it’s time to physically check the output of the MSD. You can get away with swapping most any standard coil just to confirm this test. Also where the 2 wires from the msd go to the wiring harness need to be solid. I would check the ohms at your mag pick-up. Make sure to test the 12 volt on/off wire while cranking the engine! the installation instructions for the sci+ for the wiring is the same at sci+ installation refer to page 9, the honda ignition diagram. The car was driving fine prior to MSD 6a ignition when 12volt ignition wired directly to the +coil and distributor wired to the positive+ and negative_ of the coil. 6A - PN 6201, 6AL - PN 6425 1 - Parts Bag. Generally, it will be connected to the wire that used to go to the coil’s positive terminal. Problems with the ignition system can definitely cause misfiring, and they can do so in a number of ways. Wires are stock OEM braidied wires and the plugs were gapped at 0.040. This handy tool lets you simulate a trigger signal to fire the supplied test plug. The company that is famous for their fuel system components cranked out horseless carriages and motor-driven cycles at the dawn of the age of the automobile.Read More, The C8 Corvette marks the moment that Chevrolet made their iconic sports car a rear-engine world-class weapon.

Took the truck on a small little road trip to get some firewood â¦ Sometimes, installation errors or mishaps can cause issues that prevent them from working properly. Just for fun switch the wires on the mag pickup. If you trigger the MSD through the 2-pin magnetic pickup harness, you’ll need a paperclip or a bare piece of wire. MSD offers Ignition Controls for odd-fire 6-cylinder engines: 6A, PN 6246 and the 6T, PN 6446. I have a Proform HEI distributor that i converted to use MSD by removing the 4 pin module and using the 2 magnetic pick up wires. A lot of coils are replaced unnecessarily because problems like these are overlooked or misdiagnosed. Every Ignition Has Two Sides. Simple checks that can be made to identify a misfire caused by a fuel delivery problem include checking the injectors and fuel pressure. If you’re not using the negative terminal for ground (which is the preferred method), make sure your ground source is clean, tight and there’s a path from the engine to the chassis and to the battery. The 6A is designed to be installed under the hood but is recommended to be mounted away from direct heat sources such as the exhaust system. Braided wires are correct. i also had to get a msd #8910 eis for my check engine light to not come on. Just thinking out loud, looking for possible causes of what I think may be misfire. Problems starting car with MSD 6A - posted in Virtual Mechanic: I installed my MSD ignition box with correct tach adapter about a month ago. Never had to use them. I second bench testing it. 29K 272. tomposthuma. Both of these ignitions are easy to install on nearly any 4, 6 or 8-cylinder engine running a distributor. Remember, the voltage from the MSD needs to go through the windings of the coil to build up a higher voltage so the coil could also be at fault. MSD summed up for us on their educational site what is exactly happening within the ignition process: A typical (meaning stock) 12-volt automotive ignition system operates by taking in a low voltage with high current from the carâs battery and changing it into a higher voltage with lower current to jump the spark plug gap to propagate combustion in the cylinder. Have read that a MSD ignition â¦ Another connection that should be scrutinized prior to installation is the switched 12 volt source wire for the small gauge red wire. It has a 327ci/210HP engine modified with an Edelbrock Performer intake, 4-bbl Rochester QuadraJet, Hooker headers and a 2.5" Magnaflow exhaust system as the only modifications as far as I know. Remember, these units have a one year warranty, plus most of the 6A series can be rebuilt so it’s worth sending the unit in after you’ve taken the proper steps and checks. Easiest way to see if the box is to take it out of the circuit electrically. The rotor is the NAPA non resistor rotor and brand new cap. Make sure the wire is away from any fuel supply or fumes as you’re going to be causing a spark to jump from the wire to ground. I put my MSD 6A ignition box and the MSD coil on the other day. geNerAL WIrINg INFOrMATION. One common question in regards to MSD Ignition controls is âWhy isnât 12V power on the orange (COIL +) wire?â The main reason 12V wonât be present at coil + is because your MSD ignition is a Capacitive Discharge Ignition. I also wanted the rev-limiter. When it is varying like this I can hear the motor sound good and bad as it fluctuates. Low coil output can also be caused by a faulty ignition module or a faulty coil driver circuit inside the PCM. Intermittent issues can generally be tracked down to a faulty ground or loose connection and if you have trouble starting your engine, there are easy steps to take to confirm the operation of your ignition. Wire Length: All of the wires of the MSD Ignition may be shortened as long as quality connectors are used or soldered in place. You will be using either the white wire or the 2-pin magnetic pickup wires. I used to think the same, but proof is in the multiple dyno graphs . That said, if you’ve experienced an issue or no-start situation, there are several items you can easily troubleshoot to assist in determining if the ignition is at fault, or move on to another system on your vehicle. A multimeter is an essential tool to any automotive electrical diagnostic test. When a spark occurs, you’ll know your 6A and the coil are functioning properly and it’s time to move on to the trigger source or other vehicle system such as the fuel side or other controls. It is best to route this harness away from the two coil wires and any spark plug wires. The only two wires connected to the coil are the Orange and Black wire from the MSD. Facts that may or may not be relevant : I run an MSD 6A ignition, 6 mos old NGK plug wires, NGK plugs, stock heat range, overgapped to .045-.050, and an MSD blaster 2 coil, which is about 3 years old and kinda beat up looking (this is one suspect).Last I checked, compression was good and even at 120-125 psi â¦ MSD offers a couple different Ignition Testers such as this Single Channel Tester, PN 8998. Before getting into those steps, let’s review a few installation tips to confirm the system is installed properly and for best operation. I went out for a test drive and I couldn't tell any difference (not expecting much noticeable performance difference anyway). the wires inside my distributor were blue to the pick-up and black to the coil. MSD works, but I have seen some people with problems. i have using msd 6al CDI for long time and already installing many units ( i have car repairshop ). To lengthen the wires, use one size bigger gauge wire (10 gauge for This ignition works on modified street machines, trucks or street rods. I don't have a 6AL, I have a 6A, and it runs perfect with my HEI and vacuum advance setup. In your application, the white wire is not used. Note: MSD offers Ignition Controls for odd-fire 6-cylinder engines: 6A, PN 6246 and the 6T, PN 6446. Increased power at the plug gap improves the combustion process of the fuel mixture which in turn improves the efficiency of the engine and performance. A spark should jump when you remove the short. When it starts it runs great. The plugs and wires look fine. Simply remove the coil wire from the distributor and position it so that it will show a spark from the coil wire to ground on the engine. Bad spark plug wires are another common cause of misfires. The tester simply connects to a 12 volt source and ground plus is supplied with a clip-on test plug that puts a small load on the coil that connects to ground. Ideally, the ground wire would also be connected to the battery, but it can also go to the engine block or chassis ground – but make sure there is a quality engine-to-frame ground strap. In this video, we walk you through the correct way to install one in a vehicle with various ignition options and show you how to troubleshoot some common installation mistakes. Are you sure the wires to the MSD trigger from your distributor or crank trigger are not backwards? Remove the coil wire from the distributor cap and place it about ½” from ground.

Your troubleshooting should always start with the battery terminal connections while confirming the condition of the battery. I had a msd 6a in my 82 and it was flawless. It has some (tentative) advantage of being a capacitive discharge system, so it can give hotter spark, longer spark,or multiple sparks. This wire turns the MSD on and off with the ignition switch. The battery needs to be fully charged and in good health, then check the MSD connections to the battery positive terminal as well as the ground. This Tester, PN 8998, simulates a trigger signal on the mag pickup or white wire of the MSD and has a digital read out allowing you to ‘control’ the rpm. Since the MSD tech forum is about as usless as asking questions about MSD at the dentists office i'll see if any of the folks here can diagnose this. MSD supplies a white wire from the 6A box that triggers the box when using a points-triggered distributor. (Make sure the car is in park and all wires are clear of the fan and any moving parts.). This is very important as on a lot of older vehicles there was a bypass that supplied higher voltage to the coil during cranking to assist in cold starts. Depending on your application, either tap the white wire to ground on and off to trigger the ignition or short the violet and green wires on and off. Without cranking the engine, turn the key to the on position then take the paperclip and short the violet wire to the green wire of the 2-pin connector over and over. i know i should have soldered it and i think i have an fluctuating voltage going to the box.
