I test muy block heater with one of those live wire testers that you
just have to touch the cable and it beeps if current is going through
the wire. I think you know what tool 'm talking about. Got mind at CTC
for about $14 on sale.
They tested it at the dealership with something similar, said it's fine.
I put an ohm meter across it and got very low resistance compared to the
heater in my wife's little car.
It has continuity, but I don't think it is making heat.
I would think a block heater would have to have a higher resistance.
After all, isn't it resistance that causes it to heat up? Somewhere
there should be a specification telling what the DC resistance should
be.
If it turns out yours has a substantially lower resistance, it would
indicate to me you've got a defective heater.
I'm guessing here that the block heater heats the coolant? In that case,
is there any way to measure the temperature of the coolant while the
heater is plugged in & turned on?
