Re: relay for offroad lights?
Could have been bad connections at the relay. Where did the relay melt...
at the terminals? As DougW says 12.5 amps each but that is pushing the
limit of a $6 relay. And to Bill's point, if you have less than 12 volts at
the relay, the current goes up and then you approach the "30 amp rating" of
the relay. You could use a starter solenoid.

Re: relay for offroad lights?
Good point, Lon, on the Bosch relays. They are socketed, but you can buy
the socket prewired, so all you have to do is cut and splice. In my
opinion, there is a reason that the major manufacturers use Bosch relays.
There are dozens on any given car, and they generally last the life of the
vehicle.

I just plug in connectors without sockets. I get 6 or more of them for free
from every european car I see heading for the scrap yard. BMW's Bosch relays
have the terminals in the same configuration, but are wired differently, but
have the schematic on the case.
