Electronic Ignition "Orange Box."

[Russ Hood]

My car wont start and has electronic ignition. Is there a way to check and see if it is bad? I looked on classic industries to buy one but it looks like it comes with the distributor and I dont need that.

Suggestions appreciated........

I read that the different color boxes are for different RPM range. Like the blue and silver is that right.

I have not been on here in a while. I have been testing the actual RPM that the boxes I have come across run on my mock up. Tell you what having the right balllast resistor makes a big difference.

This thread we beat the hell out of ECU's. Tons of info in here just jumps around alot. Biggets thing covered is how to tel a good box from a cheap knockoff which are abundant now.

1974 Brain Box saves the day.

There are a bunch of Knockoff MP orange boxes floating around out there lately biggest clue is if it has a real transistor or not on top.

How to tell a "fake" ECU from a real one

There are a ton of fake ecu's out there two easy wats to tell at a glance are the height of the transistor, usally the fake ones are around 3/8" high and a real one 5/16 or so. Another way to tell at a glance is if there is printing on the...
