[jamies98lsc]

does anyone know what the electric fans in the mark VIII's draw for amps? someone is asking me, because its for a project car not another mark. any info in appreciated.

I think on high it's somwhere around 70 amps but I'm not 100% sure.

Can you just look at the value of the fuse /circuit breaker for that system and tell???

The startup amperage is higher and that's why the fuse is rated so high, but I tested mine and it runs at 20A on high speed.

I believe its a 40 amp fuse

as they get older they draw more current as the bearings go out

The way to really find out is to clip a DC amprobe around one of the wires to the fan motor.

I bought a DC amprobe a few months ago for checking starter draw on Outboard motors.

It's a important figure when moving batteries and installing the correct size battery cables.

The problem is that no outboard Factory manual lists this info.

This is the one I have.

That's exactly how I measured mine.
