Marks02 Posted March 6, 2020 Share Posted March 6, 2020 (edited) My 1980 Brat ea71 is having an ignition issue. There is a box located right next to the coil that says "transistor IGM." It malfunctions whenever I hit a bump and the car studders and I lose tachometer function for a split second. It stopped working completely once. I got out and traced the wires from the disty back to this box. I banged on it and it started working. I punched in the numbers that were on it and nothing even came up. What is it and where can I get a new one? Thanks!!! Edited March 6, 2020 by Marks02 Quote Link to comment Share on other sites More sharing options...
naru2 Posted March 7, 2020 Share Posted March 7, 2020 That is your ignition module.Subaru also calls it a control unit. Wreckers are the only source I know. 80 Brats and all 79 4wds have this part. Might be worth opening it up and resoldering. Pretty sure you could use a later style disty w/an internal module if you are unable to locate this part.

Rampage Posted March 7, 2020 Share Posted March 7, 2020 Try this site. I used zip code 86402 and two listings showed up. One in Ontario and one in Virginia. They list it as Ignitor/Coil. You would have to call the yards to see if the Ignitor is still on the coil bracket and if they still have it. Some of them take a long time to remove their listings. http://www.car-part.com/index.htm Have a look at this post. It is two pages long. See if your part looks the same. https://www.ultimatesubaru.org/forum/topic/170502-can-someone-tell-me-where-i-can-get-a-ignition-transistor-or-is-it-possible-to-bye-pass-it-on-a-90-loyale/ If I had more info on the part I think I could make one.

Marks02 Posted March 7, 2020 Author Share Posted March 7, 2020 Thank you both for the help. I think I'm gonna go with a newer disty. I've tried to find one before and came up with nothing. I know that it needs to be from an '83 or newer N/A EA81. Quote Link to comment Share on other sites More sharing options...
Marks02 Posted March 8, 2020 Author Share Posted March 8, 2020 So I've found 2 different distributors on rock auto. I know that they are odd brands, but I need one. Which one of them should I get? And will one of these solve the issue? Here's the link. https://www.rockauto.com/en/catalog/subaru,1983,brat,1.8l+h4,1267691,ignition,distributor,7108 Quote Link to comment Share on other sites More sharing options...
naru2 Posted March 8, 2020 Share Posted March 8, 2020 Either should work as they both have self contained ignition modules,but,the Hitachi is slightly more robust. Quote Link to comment Share on other sites More sharing options...
