RRC Ignition wierdness

Getting the lwb buttoned up and it's decided that it doesn't want to start ("Ran when parked!") A PO installed, poorly, a battery maintainer that is somehow wired through the alternator. It now cranks but doesn't catch and, here's the truly strange part, if I take the key out of the ignition, the interior lights and the battery warning light will stay on until the battery is disconnected. Also, the alternator is new and the tach doesn't work.

While there may not be causality between the battery maintainer and the no-start, I would like to ensure that the wiring is correct at the alternator, amplifier and coil. Does anyone have a cheat sheet on what goes where? the Manual isn't proving to be helpful.

Many thanks in advance.

Not sure what year you have but my '94 did something similar and it turned out to be a cut off switch I accidentally depressed under the drivers seat. Idk if that's standard or unique to mine but thought I'd throw it out there besides the obvious started, ignition and battery stuff

Do you have the Marelli alternator? The white wire is the tach wire and goes on the spade terminal (looking at the back of the alternator it is the one on the far left). The brown wire is the alternator charge lamp on the dash which is connected to the small stud terminal (middle), and the big fat brown wire is the battery connection (right).

white tach wire has a blade type connector, and brown charge lamp wire has a ring connector held on by an 8mm nut to keep anyone from messing up.....

Things are starting to reveal themselves. There is no white wire going to the alternator, and I can't find one hanging out immediately -- that will need some research. That accounts for the no tach issue. On the no start issue, the white/black wire going to the coil separated itself from the coil at the spade connector when I looked at it funny. That could well be the no-start issue. I'll reconnect in the daylight and see what that yields.

Anyone know if that ignition suppressor actually does anything?

Success! Found a wire that had broken in the spade connector at the coil, fired right up. Battery light and interior lights still stay on with key removed, though. And ideas on that?

Next step: find alternate wire. Can someone trace the white wire from the alternator back and tell me where it physically goes? I've unwrapped the bodged harness that the PO created in the installation of a battery minder and I'm trying to get it back to stock.
Thanks!
