    What should be connected to this? I found a cut wire connected to this and I want to be sure all is ok. I currently have just the two wires connected to it.

    On my burb, the side that your 2 wires are on i have one wire going to the starter and another wire going to the alternator. On the other side(drivers side connection)it goes to the backside of the fuse box on the firewall. IIRC its part of the ignition circuit /forums/images/graemlins/thumb.gif

    Should be the wires from the starter to the fuse panel connector, and in some cases factory towing package wiring.

    The two wires visible should come from the starter, and two wires should tie into the fuse panel connector from that junction.

    Well, I thought it was only the two wires from the starter, but it could be from the alternator too, or instead of, either of those wires. Been awhile since I messed with mine.

    If everything works ok, I'd probably forget it, but I would first make sure that anything thats supposed to have a fusible link, does. Or else you could have a nasty meltdown.

    For one thing both red wires off the starter (not the + batt cable) need to have one each as I recall, and not sure if there are usually two more fusible links on those wires at the junction also.

    Have to venture a guess that someone rewired the thing. When messing with fuse panel feeds, I'd want to make sure the fuse panel is at least protected by the fusible links.

    Does your fan work? The 3rd wire on my rig runs to the heater/AC relay.

    That is where the a/c system gets its power...the two wires that power that junction block should be fuse links...provides power across a shunt to power the a/c system.

    Per my 1990 service manual this is the "Accessory" conector. This is were you connect the charging cable for the second battery and what ever else you can think of. It is fed directly from the alternater.

    dan..
