Wondered if anyone might know this - been looking at the electrical manual but can't see much.

Got a break in my small connection to the starter motor, looking at a cut out and splice some new wire in, but wondering what sort of draw that has. Only got 10amp wire to hand, but this looks like a fair bit beefier than that.

Thanks

Grue,

according to the wiring diagram the starter solenoid has a 40 Amps fuse in series on my 3.2

Its safe to assume less than that.

But if you splice in a wire that can handle 40 Amps for 20 seconds you should be fine

Good Luck

Paul

According to the wiring diagram, the starter trigger wire is 4.0mm, so considerably more current than a 10 Amp cable will take.

Thales guys, apriciate it. Picked up some decent wire and should be on road again soon

10 amp wire is a meaningless statement.


Let's say you have 40 amp & are using 10awg 5.26mm² wire. 1 metre will have a percentage loss of 0.965% at 25°C at 13.85 volts or 1.113% at 12.0 volts.

Double the length, double the loss.

Or double the amps, double the loss.

Or double the cross sectional area, halve the loss.


Typically a 3% maximum loss is acceptable for less for critical items. Add up compounding losses, like more wire length within a component like a fridge (0.17 volts for my fridge at 3.8 amps)

& the calculated length of wire is the total length of both + & - sections of wire. Procrastination, mankind's greatest labour saving device!
