I just fixed my courier, the mitsubishi ignition on the 2.3 ford engine finally quit after 500K+ miles, It just fell apart. Well I wasn't about to spend a bundle on a new/rebuilt mitsubishi unit so I got a ford duraspark II unit they are both magnetic pickups. The damn thing runs great but I just noticed the mitsubishi ignition module gets hot. Any ideas?

 

Moved to the Electrical Forum.

 

I thought you replaced the Mitsubisi module?

 

He must have a duraspark II dist mated to the mitsu module. You could go full duraspark II with a little head scratching.

 

Yeah I mated them, They are both magnetic(reluctor) pickups which all work about the same. And it works great, it even seems to accelerate better but the module is getting hot and I cannot see how it could. The pickup coil cannot draw the current, even shorted the loop cannot be more than a couple of hundred milliamps

 

May it's something to do with the pulse width it receives. Maybe that's changing the duty cycle of the coil circuit in the module. If it sends voltage to the coil with a little longer duration, maybe that's causing the extra heat. Just a guess.

 

Hmmmmn.......I don't think changing the distributor pickup coil would cause this. Can you put a heatsink on the module? Or maybe have a Durospark module ready to install? Modern electronics can take a lot of heat.
