Thread: Isuzu County wire loom - fire

Have you seen this: Circuit Breaker Kit 40A, Perentie - KLR Automotive

A glaring fault in the Perentie (and early 110 as well) wiring harness is the unfused battery power that passes into the dash (on multiple wires). With age these wires can chafe and short out, usually melting the main wiring harness in the process (and some parts of the dash as well).

Hopefully doesn't happen to anyone else and this thread prewarns.
I had put a fusible link on the alternator output, a cut out switch on the winch and multiple fuses on any new circuits.
But....as pointed out, this live feed wire is not fused.

I have no electrical experience short of installing a couple uhf radios, so this is a huge project. I either repair or write this vehicle off...and I can tell you I love my Landie and have owned this for many years.
I have spent the last week slowly labelling what I can, taking lots of photos to help remember what colours go where. I have a Dyno label machine to label. I have the Australian supplement handbook with circuit diagram.
I have removed both wheel eyebrows on front guards and removed the harness from starter motor to alt. and across firewall to back up relay.
The starter wiring was very difficult to remove as the retaining nut was too close to chassis. I had to remove to three retainers and wiggle it to give room.
The main harness goes to the head lights and indicators.
Removed steering wheel and dash panel.
The speedometer only showed current speed, the trip meter didn't work and the lights didn't work. No wonder on looking, the bulbs have melted into the back...Will make sure the bulbs next time are correct wattage.
The harness is now free across the dash but is still jammed at back of dash where the harness enters the firewall.
My problem is that I have under dash a/c unit that looks like I will need to remove to finally remove the harness to get it onto the bench.

I need some help from the Forum.
I have a Backup Relay with 6 pins that was up near the brake booster.
I can't find a part number to replace it.
It is JEDICO with some numbers 5 82550......
Part of it has melted where the main power wire went (Brown).
Thank you

Not this one? It's an alternative engine stop relay for the Isuzu.

The other stop relay is this one:

Although they are only 5 pin.

Hi Ron,
It definitely is 6 pin, it is a relay to ensure that reverse lights can only be activated when oil pressure has activated relay eg on only when engine running.
It has Grey wire goes to oil switch, green going to reverse circuit, Black, two Browns and brown/white which is the dash oil light. Not the isuzu stop relay.
It is the "back up Relay" in electrical circuit diagram, 3.9 diesel models. Unfortunately, can't find any part numbers.
Cheers,
David

Yes, the reason for that is to stop the reverse lights flattening the battery if the vehicle is left in reverse with the ignition off.

I'll be going to KLR sometime next week so I can ask Brad.

Hi Ron,
I think I am over thinking this. So long as I have a 6 pin relay, know what the coil activation pins are and NO and NC pin sets are a 30 - 40 Amp Relay should be ok.
So I will keep plugging on slowly.
Thanks
David
