Tail lights go on then after a short while they are off all other lights stay on


Double check owner's manual, troubleshooting. Sounds to me like an issue with connections most likely at the switch, bad switch, or possibly a ground that serves the taillight assembly. Do all lights in the taillights go out? Brake, turn signal, parking, and Backup? If so more than likely the "ground wire" that serves the whole tail light assembly serving all the above-mentioned lights is apart or bad connection. It's an uninsulated wire that "should" be attached to the body metal with a screw. The attaching screw, or body metal may be rusted at that location resulting in a bad connection. Clean to bright metal both the location and lug. there may be a similar connection issue in the Taillight assembly.

2000 jeep grand Cherokee limited only blows cold air despite c.c setting position. Also what I'm Guessing to be the blower control module hot lead burned through end of wire/ wiring harness/ and circuit...


lead burned through
that's easy
using the wrong fuse size
and the feed is shorted,
the correct fuse prevents the burned wires.

here are the HVAC pages
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

lots of things can short. in cars. (topic Hvac)
  • the wires.
  • the connectors
  • the HVAC motors (actuators)
  • the blower.

if you had stated the exact wire color and what it connect to exacty
we can state who shorted.

Fuse 1 , 40amp runs the blower. dark green.
Fuse 20 , 10amps runs others.
Fuse 7 runs zone control,,,10A and all 4 damper motors actuators.
see 8w-42-6 pages.

ok you have your FSM and now can find who connects to what.

Lets start with make model and year.
And for the record, you will likely need to tear apart that harness because the other wires are now melted together.

your hot wire was grounded when it sparked, it burned the fuse involving that circuit to protect from a short , just replace burnt fuse inside of fuse box.

My mig welder will not make an arc


There is a small chance the transformer burned out, but more likely the switch has dirty contacts or burned out. If you turn the switch through all heat positions 2 or 3 times before you start welding in the morning, it should remedy it in the future. In the short term, spray some contact cleaner (or even WD 40 in this rare instance) into the heat selector switch and rotate it through the ranges a number of times to remove corrosion from contacts.

Will the wire arc when dragged across the ground clamp? If not- there are internal fuses in the machine and they may be loose or blown. There should be one in series with the "hot side" (the gun) of the circuit and sometimes on the ground clamp side of the circuit.

There is a small chance the transformer burned out, but more likely the switch has severely corroded or dirty contacts or the switch burned out.

'95 Bonneville SSE won't start


Check for a burned out fusible link at the junction where the positive cable bolts to a stud.1994-1995 may be on the starter,connected to the large hot cable on starter.The fusible link,if burned out will pull apart like taffy.It looks like a regular wire,but like I said,it will pull apart like taffy,if it is burned out.Replace them with the same size fusible link,not a wire,you wil set the car on fire if you do,and there is a short.After you do this,check for a possible reason this link burned into,something caused this.Low battery,or bad starter,plus holdind the kay in the start position trying to start the car with a low battery,or bad connection,or bad starter,will cause tis problem.I hope this was helpful.

If you had a short that large before you started working on the batt cables, it would have burned long before it did. Check your work over and see where it's grounding. You can make a temporary link by using a new piece of wire the same as the gauge at both ends of the link and sectioning in a short piece of smaller ga. wire. Hopefully you didn't damage the alternator or other electronics. The original problem sounds like possibly the fuel pump anti drain-back valve is bad (integral with pump) Testing pressure will verify that.
You can disconnect alternator, but the fuse method you mentioned sounds more reasonable.

  1. Check the wiring of the new radio installed as follows..
  2. Disconnect battery ground
  3. verify radio ground wire is grounded to metal
  4. verify radio hot wire (normally red and thick) is connected to a power source that is off when the ignition key is in the "off" position.
  5. verify that the always hot wire is connect to a constant 12v power supply even with the ignition off.
  6. make sure the pwr antenna wire if not used is taped at the tip and not touching any metal.
  7. verify that all speaker wires are connect correctly and not shorted to ground.
  8. connect battery ground you may get a small spark if your courtesy lites work.
  9. start engine verify your battery is charging by disconnecting the battery ground cable while the engine is running, it should continue running if it don't, alternator maybe bad.
  10. If it continues running problem solved..
