What does the loom do on an Isuzu trouper My Husbands diesel Isuzu trouper has trouble starting it is intermittent the garage has told him it is a cracked loom?

Answer 1

You might want to ask the mechanics at the garage to double check this; but generally a loom refers to the place where the wiring harness goes through the firewall. If your wiring harness is messed up it will cause all kinds of strange electrical things to happen. Replacing electrical components will not help as they will still not function correctly. The cause is shorts at different places in the wiring. This is usually caused by cracked insulation on old wires. Intermittent starting problems are often the result. Painless Wiring makes harnesses to order for almost any vehicle and I recommend them. They run from $300 to $450.
