Reply to "engine will not start"

I know that many car enthusiasts are completely out of their depth when it comes to electrical work and i have seen wiring in cars that a 10 year old would be ashamed of.

Some years back i made a electronic conversion for Chev engines to fit in the early model small distributors.

I gave the whole thing away because of the number of cretins that would not follow the instructions of how to wire the system up.

I had "customers" that even decided the earth wire on the ecu was not necessary and removed it even before installing the system. Consequently it did not work and they blamed me for it. Doh !

So i can see where MSD are coming from when they give explicit instructions on how to wire up their boxes.

I wired the MSD boxes up to the letter of the instructions and as others have found the boxes can still mysteriously fail without any warning.

When they work they seem to work well and i like them but the possibility of instant failure usually at the most inconvenient time puts me off them.

I'm still looking for someone that actually knows what the fault is that makes them fail.....
