sierra ignition switch current rating?
DanP - 17/4/06 at 09:32 PM

having just seen the post regarding running the starter solenoid thru the ignition switch, does anyone know what current the sierra column ignition switch is rated to (in position 2 specifically)? can i just run my ignition live wiring straight thru it or is it best to use it to switch a relay?

Cheers.

As the standard Sierra setup does not uses a relay there is no reason to use one - that includes the starter solenoid too.

eeek, thats a lot of current, I'd add the caveat that make sure your cables can handle it. Things like the Premier Wiring Loom probably expect a solonoid.

AFAIK every setup uses a solenoid for the starter - just not a relay for the solenoid as it probably draws around 8 Amps which any 0.5mm2 cable and switch should easily handle. The starter motor can draw up to 700 Amps which is why the solenoid is there in the first place - it is just another form of relay.
