I am in the process of installing a Redarc Dual Battery system in my 2000 Petrol 100 Series. The battery trays are on the far left and far right hand front side of the vehicle.

What is the best way to route the positive cable. I don't particularly want to go over the top of the radiator so I could go behind the bull bar or behind the motor. Any ideas?

Also is there a good position on the chassis for the negative ground? Any photos would be appreciated.

Hey Punter. the cable on my 100s. runs along the back of the fire wall and for the earth wire just look for any of the original earh straps on the vehicle and bolted cable to it . i hope this helps.
cheers.

I have the same run as Jason and it is neat, tidy and out of the way.
I was told I needed the 200amp isolator because of the wiring system in the 100s. It's been in for over 2 years and no problems.

Punter you can run the cable in front of radiator (behind grill). feed it through holes for head lights in radiator support panel. cabel tie it up under support panel. shortest distance less cable.

Hi, my only concern with running the cable across the front is damage to the cable in the event of a front-end prang and the resulting fire risk if shorted. A similar risk exists with electric winch cabling. Encasing the cable in some flexible electrical conduit would help.

joc45 I have mine in conduit (100 series). As to damage in a front end prang the batteries, h/lights, driving lights, factory wiring etc is all in the front of car already. just thinking the risk of fire (in prang)would not be greatly increased? (but im no sparky).

Hi crewser,
Yeh, all those bits are at some risk in a prang, prob the battery and winch are most at risk, coz they're unfused at that point; similarly, the second battery would be unfused. Most other wiring is fused, so risk is less.
A concern is when there is an electrical short causing a fire, the insurance may not honour a claim where they see mods, but for original wiring, even if it is poorly run across the front, the insur would have to pay out. Silly, isn't it?
I ran the battery combining cable around the firewall in conduit, but the winch cable I had no option but to run in the front, but in conduit.
I recall that the 100 series diesels combined the two standard batteries with a cable across the front. Didn't like it.
Perhaps I'm over-cautious....
But then, bull bars protect everything, don't they? ;-)
cheers, Gerry
