How to replace the fuse box above the battery?

Replace the box. Get a 49″ #4 battery cable from parts supply house. The wire will have eyelets on each end. Use one eyelet and remove the other. Replace the missing end with one with a smaller hole; I found one at tractor supply. Next remove part of the stock so the end will fit the new fuse box.

What causes the fuse box above the battery to overheat?

It tends to get a break in the wire near the fuse box that then arcs and overheats; this is not a problem with a short otherwise the fuse would blow, this is an arc. I have a 2005 Golf MKIV and it did this also. Lost a/c, fans, overheated. The B+ wire from the alternator to the battery appears to be too small a gauge.

What should I do if my Fuse Box is melting?

All connections are to be cleaned to bright metal. Stabilant 22 will be painted on the faces of the bolted connections. Ensure that the bolted connections are not subject to vibration that could loosen them over time. Consider adding tie downs for the wires near the fuse box if none exist. 2) Now test the circuit.

Where to put stabilant 22 on a fuse box?

Stabilant 22 will be painted on the faces of the bolted connections. Ensure that the bolted connections are not subject to vibration that could loosen them over time. Consider adding tie downs for the wires near the fuse box if none exist. 2) Now test the circuit.

What to do if your fuse box is clicking?

If that relay also clicks constantly, you need to run more tests. If that relay works fine, then the original relay that was in that spot is faulty. Simply replace that relay with a new one. Identify the terminals on the relay. Look at the terminal labels on the relay.

What are the terminals on a fuse box?

Look at the terminal labels on the relay. They are identified as 30, 85, 86, 87 and 87a, if it is a five-terminal relay. Terminal 30 receives constant battery voltage. Terminal 85 is the relay’s connection to ground, 87 and 87a are the output terminals for whatever the relay controls and 86 is the power to the control side of the relay.

What does a relay do in a fuse box?

Relays control a high-current circuit using low current. It makes it possible to control things like the headlights and the fuel pump without running high-amperage current into the passenger compartment. Try swapping the relay. Remove the relay from the fuse box — It pulls straight out.
