Ahh! Electrical Help!!!!

Hey everyone! Here's the rundown:

1999 Cherokee Sport
4.0L straight six
Auto tranny

I bought this thing back in November. At the time of purchase there was a toggle switch. Looking at the wiring one wire runs to the + post of the battery with an inline fuse, while the other wire is spliced to the green/orange strip (this wire is the power wire to the ignition coil).

It's now March and I've already gone through one alternator (which isn't cheap). The lights still pulse bright/dim under 2000 RPM. The old alternator was dismantled and cause of failure was determined to be a grounding through the alternator shaft itself. I guess it somehow caused the rotor to touch the windings and ground a spot. Either way, the electrical grounding through the shaft is what worries me. Does the make-shift wiring the coil backleading and causing my alternator to fry prematurly, or is there something wrong with the battery? In any event I need help to figure this thing out. Thanks everyone!!!!

Explain this switch better.. What is this green and orange stip, is it factory? what happens when youflip the switch? Engine kill? And the last alternator possibly touched due to a bent armature, bad bearing, warping of the case and a few others.. but I doubt that it had anything to do with this switch unless someone really hacked this 99's wiring..

I agree please explain the wiring a little more from the sound of it, it was wired so that you could shut down the ignition coil from inside the engine bay. Maybe it was some sort of as CowboyPA said "Kill switch" like so you could park in a crappy neighborhood, and in order for it to get stolen they atleast couldn't drive it away.
If those are the only two things it joins, then it is realy unlikely that it has anything to do with your alternator issues(to be sure, take it out-in a short term trial sort of way). But your voltage issues could be so many things, do you have aftermarket audio at all, or other lights, or C.B.?
Chrysler did a s&^$%&^y job engineering the wiring on not just these but pretty much all their products.

I dont think a wire running from the battery positive to the coil would be a good kill switch sounds like a bad hack job,what happens when you disconnect the wire from the battery?

ah,beer the cause of and cure to all of lifes problems ...Homer J Simpson... I am the guy in the red jeep!

Try starting your own thread, instead of digging up a thread that has been dead for 7 years.

Replace your battery and alternator wires with larger gauge wires. Install a higher output alternator. Install a capacitor for your amp.
