Headlights are too hot

I seen lot of time on the battery on top remove the plastic cover leave the car running and check if the fuses therminal get hot if so remove the nut and clean the contact but be carefull it get very hot dont burn yourself hot enough to melt the plastic inside that a great video example but you dont need to change it repair it good luck pierre p.s the black wire is the most common one to burn that the alternator feed

Normally this condition is the result of a poor body ground connection. Testing for this can be deceiving. At the static(nothing on) condition, testing can show a good ground. However when a circuit is excited, it has a determined resistance and a set current flow. If the ground connection to this or a branch circuit is loose, corroded, or broken wire. This will allow just enough connection to show as being good, but not good enough to complete the circuit with the required amount of connection when energized.

check low beam fuse when switched on if it has voltage registering across the fuse ,if there is voltage across the low beam RHS fuse then it is possibly a pinched wire from the headlight running back towards inside of the car

No. Dash lights being out could be a bad headlight switch, since the dash lights are routed through the headlight switch, not the dimmer switch. Park and tail lights also controlled by the headlight switch.

Hi, Those have a fuse in the positive battery cable located in the middle of the cable about the center of the firewall on its route to the starter. I would check that fuse before proceeding. Also, those cables are known to go bad, My daughter had a 2000 cougar that kept draing the battery and lights wouldnt work right sometimes. Eventually it fried the alternator. After replacing the alternator and battery cable, it worked fine. Try the fuse first, If it is blown, I would recommend replacing the cable to cure the headlight problem. Mike

Check all the bulbs at tail end for parking and brakes, test grounds and harness for trailer. Check fuses. clean batery terminals, Re instal head light swich properly and make sure all wires conect.
Vitally

there are more wires that you cannot see that are melted that is causing the problem. trace all of your wires, starting with the license plate light, all the way to the headlights

check to see if u have voltage pulse 12v at the socket with a test light . ir not you shoud repair wiring between flashr unit to signal socket. good luck

If u have been jumping wires and such u may have burnt out a circuit, the next thing to test is the headlight swith, pull it out and look for overheated terminas and any melting of the connector to it, replace both connector and switch as ness.

The reason the fuse blows/melts is because there is excessive draw. The other alternator could be wired wrong. Check to make sure the wires are correct gauge.
