subarusaver Posted December 24, 2014 Share Posted December 24, 2014 May be a long shot, But I had an 83 Dodge van once and it Honestly melted 13 regulators and ruined 14 alternators!! Poor parts guy must have really liked me.........I was ALOT younger then,and there was no internet to search.... Finally went to an Old guy( Love Old Guys' experience) He told me "It's not grounded properly".............Five bucks and a ground strap fixed my agonizing issue!! Possibly a bad ground, maybe rusted connection?? Body must be grounded to engine,frame,etc. Good Luck!! Quote Link to comment Share on other sites More sharing options...
naru Posted December 24, 2014 Share Posted December 24, 2014 A few things come to mind. 1 Your coil is incompatible w/your distributor. Some coils will draw more current than the ignition module can handle 2 Open plug/coil high tension wires or a very bad cap/rotor. This can send high voltage back into the module,destroying it. Often,the car will run normally up to that point. I`ve seen this failure mode several times. 3 Alternator overcharging? Voltage too high? 4 Check the ground wires as suggested.

MR_Loyale Posted December 24, 2014 Share Posted December 24, 2014 Stores like Autozone and O'reilly's will put your alternator on their bench and test it for free. Quote Link to comment Share on other sites More sharing options...

And is the coil a stock subaru one? Also....how are you determining that the module is "popping"? We need more details Quote Link to comment Share on other sites More sharing options...
ScottyBigs Posted December 24, 2014 Author Share Posted December 24, 2014 Alternator is fine, maybe could check the grounds one more time, the coil is a cheaper the stock, accel super stock coil, accel 8mm plug wires and E3 plugs. Quote Link to comment Share on other sites More sharing options...

We need more details I wired the fuel pump just by itself because it was burn up a fuse wire every time it would pop that mod, in the dizzy.

Gloyale Posted December 24, 2014 Share Posted December 24, 2014 the coil is a cheaper the stock, accel super stock coil, Bingo. Get a proper coil. Accel "racing" stuff is Junk......think about it.......Cheaper and made for short trip/infrequent use "racing". Not day in day out 100's of thousands of miles. I have never seen an original EA subaru coil fail. I've seen it once in an EJ. I wired the fuel pump just by itself because it was burn up a fuse wire every time it would pop that mod, in the dizzy. Not following you here. If you've got fusible links burning........there is a short somewhere. Again, how is the coil wired? Did you tap in power to the pump from the Black/white wire to the coil? It should be on a seperate circuit with a relay.....not direct to switched power at the coil. Quote Link to comment Share on other sites More sharing options...
