alexbuoy Posted October 13, 2017 Share Posted October 13, 2017 Hi all, i have an ej22 swapped loyale that has been running great for the past couple of months until now. I keep burning up the black fusible link. Thinking it has to do with the ej22 harness that i had trimmed. What can cause the black fusible link to burn up? Bad grounds? Shorted wires? any ideas where to check would be great. TiA Link to comment Share on other sites More sharing options...
alexbuoy Posted October 13, 2017 Author Share Posted October 13, 2017 and I should add that it runs great for 30 seconds until the black fusible link gets too hot Link to comment Share on other sites More sharing options...
alexbuoy Posted October 13, 2017 Author Share Posted October 13, 2017 Bingo pulled the 15a fuse for Charge and now the fusible link doesn't get hot. Gonma get my Alt checked and see if it's that Link to comment Share on other sites More sharing options...
alexbuoy Posted November 9, 2017 Author Share Posted November 9, 2017 OK just replaced the alternator with one from oreillys and IM STILL BURNING MY FUSES, but only under load like when my headlights are on. Not quite burning but the black fusible link gets wayyy to hot. What does the black fusible link tied into. if I pull my charging fuse, the link doesn't fry. Alternator wiring wrong? i've had my swap for 6 months running perfect! Please help i'm so frustrated Link to comment Share on other sites More sharing options...
andrsn Posted November 9, 2017 Share Posted November 9, 2017 I wish I could help, I just wired up my EJ swap. I'm not even sure what the 'black fusible link' is. I just have constant power direct from battery through a fuse to the ecu backup power and fuel pump/starter relay, switched power to my harness from the ign switch, crank setting to starter from ign switch and my alternator wired through the EA81 harness. 1 Link to comment Share on other sites More sharing options...

Gloyale Posted November 10, 2017 Share Posted November 10, 2017 Ej Alt is puttingout too much amprage for the old EA wiring. Run a new wire, 10 or 8 gauge, from Alt output to battery terminal. Use 1~2" section of 10 or 8 gauge fusible link wire at the battery end. This will give the Alt charge proper rated path for amps to get to the battery. Bypassing the OE fusible link and old wires. A simpler but maybe less complete fix could be to simply cut back about 12" of the White charge wire, and spice in a new wire ther to the Alt output. The old wire just can't handle hte Amps of the EJ alt. Link to comment Share on other sites More sharing options...

And is my alternator wired in correctly? obviously fat white main charge wire is getting bypassed to go to the battery with fusible link tied in. yellow wire from alt plug to black/white on harness black/white from alt plug to white/red on harness. but reading online people have said on 95+ ej alternators you need only two wires which are the white/red for the charge lamp and the main charge wire. My ej22 is out of a 1998 OBS and it's in my 1991 Loyale Link to comment Share on other sites More sharing options...
