the car runs fine when the motor is cold. but once its a operating temp, the car will blow a ignition system fuse and shut off. not sure what can cause it. but i am running a msd system from the opti to the wires to the igntion box.....

any ideas of what it could be. i am going to try and run a 25amp instead of a 10 tomorrow and see if it holds. but i cant figure out what the actual problem is.

thanks

no one wants to help a poor old boy

 

What wiring did you touch during the install?

 

i took the power off from the msd to use for a powersource for the scavange pump.... thats the first thing im gonna check tonight.

 

The MSD should be on a circuit by itself...Directly to the batt +/-.
The scavenge pump may be pulling the amp load up far enuf to blow the fuse.
I'd check the wiring size B4 you go changing up to 25A fuses...Instead of the fuse, the wiring, connectors will bite the bullet....

 

ok i changed the scavenge pump power to a different source. fixed the problem.

thanks guys!
