(1) Don't ever ever run a vehicle without the battery installed. The battery acts as a surge suppressor. If the alternator is functional and you disconnect the jumper cables or battery cables with the engine running, you'll send a huge voltage spike into the electrical system which can take out solid state circuits. (2) Since you reversed polarity of the jumper cables, number 1 doesn't apply. Number 1 is just there to forewarn you. Did you check every fuse and link in the vehicle? Did you use a 12 volt test lamp or volt meter to check for power at the fuses? Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I have a paint problem it seems that the clear coat is turning white and pealing off maybe(not the paint though) which has created large oval patterns on the vehicle can I just maybe buy a buffing wheel and buff it off, the orginal paint is still there just it might not have a clear coat on it (the vehicle sat outside for many years sometimes with a tarp on it somtimes without   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
