Msd distributor cap problems.

Since then i reinstalled it and haven t had any problems yet. So he pulled the msd electronic distributor from the old motor and stuck it in. He pulled the cap and the pickup was covered in corrosion. Checking your distributor rotor and cap to see if they need to be replaced is one way to ensure that everything is in solid working order.

The warranty on it was expired so that was making me think it was a common problem with these. This sounds much like a the firing order being wrong. Disconnect the msd magnetic pickup connector from the distributor. Make sure the ignition switch is in the off position.

These distributors must be used with an msd ignition control such as a 6 series ignition or a 7 series ignition. Remove the coil wire from the distributor cap and position the terminal so it is approximately 1 2 from a good ground. Every 500 miles i have a heavy oxidation carbon or however you call it build up at the distributor cap inside contacts as well as at the distributor rotor contact. Msd distributor cap failures was.

Posting this for my brother. I sent it back to msd and they replaced all the guts including the module free of charge. This is easily identified by a 2 pin connector with one violet black wire and one orange black wire that connect to the magnetic pickup inside the distributor. If you are using the 2 pin magnetic pickup of the msd to trigger the ignition follow these steps.

The most popular msd distributor is our standard pro billet model. I m having the same problems on my pro billet distributor seems like i need to change the cap and rotor every year and this is only a summertime fun car half the year it s hibernating. I do keep my stock distributor and the proper size wrench for the hold down bolt in the car just. Usually a faulty distributor rotor and cap will produce a few symptoms that alert the driver that service may be required.

I have a old msd cap and it is seems to be far better quality than the new ones. He s got a gm crate motor in his 37 plymouth came with an hei that wouldn t fit against the firewall. Engine misfires can occur for a number of reasons. I have 302 engine with pro billet msd distributor msd 6al box and msd blast 3 coil.
