Mine was not even a Bosch relay, it was an auxiliary light relay made by
NightBlaster or some such for their fog lights.  Rated to 30 amps.  It's
done well for me, but I must confess I installed it in summer and sold
the bus a week or so ago, so I don't know how it would do in the dead of
winter but it did great down to 20 F or so.  Hoover once told me when I
asked him about this that the draw was around 30 amps.  I think the
Bosch relay is only fused for 15 amps and I haven't heard of anybody
having problems.

Bob can give us more specific values to work with because I have no idea
:) .  The Ford solenoid hasn't given me any trouble but I've only had
the thing for a few weeks, we'll see how it holds up.  I jsut don't like
the idea of anything for a Ford on my VW -- Ford does not impress me :)

Yeah, I'd say you're right.  It's too cold to mess with it now anyway :)

Take care and thanks for the response,
