ea82t wiring problem
ea82t wiring problem
gday, has any one got a link to a 4 plug ecu pin out for a ea82t. just finished conversion on brumby and have no spark. Ive searched on here but all i can find is the 3 plug pin out. any help would be much appreciated. thanks

maybe contact some that have posted in here refering to 4 plug ecu

From what i recall there was not much difference between the two, but the obvious fourh plug is missing.
Did you buy a conversion kit from someone or shift it from your donor to your Brumby
Stick in here until you get it
Mark has beaten me to again, twice in the one day Aussie time, only seven minutes apart.
Well done with the info - more useful than mine. Guess you scored another friend here

I'd be chasing the basics from the plugs back to the dissy cap and ignition power to the coil .
Other than that the system merely takes signals from the computer for the transistor to switch the coil on/off .
There should be factory WSMs online with troubleshooting sections for the 4 ECU plug ignition system .
A bit of the flow chart .
Disconnect injector connector .
Disconnect Crank Angle Sensor at distributor .
With ignition on ,
1) Check voltage across the body side terminal R of CAS plug > 10v
2) Ditto terminal B of body side CAS plug > 4v
3) Ditto terminal W > 4v
Reconnect CAS plug .
Disconnect two pin plug from power transistor and switch ignition on .
Check if the monitor voltage repeats to become 0 and 5v as the engine is turned slowly (by hand , do not crank with starter) between control unit position signal terminal 8 (B) and car body .
Ditto though cranking with starter while monitoring control unit reference signal 17 (W) and car body .
Reconnect two pin power transistor plug .
Reconnect injector connector .
Ignition on .
Check voltage Ignition coil (+) > 10v - if no replace coil .
Disconnect two pin power transistor plug .
Check if voltage varies synchronously with engine revolutions when cranked with starter while monitoring the voltage between the two pin plug terminal (WY) and the body . If yes replace IG coil . If no repair harness or replace control unit .
It doesn't hurt to continuity test any relevant wires between the computers four plugs and the CAS and two pin transistor plug terminals .
They get you to disconnect the injector plug so you don't flood the thing in the at times drawn out start ya bastard phase ...
Lets know how you go , cheers Adrian .
Any Qs ask away .
