Just wired in a 42"? Light bar , I have wired it into the relay terminal that supplies power to the two front spotlights .
Turned on high beams and lights worked for about two seconds and blew the fuse ( glass 15 amp) , checked wiring , all ok found another 15 amp fuse and same again after about two secs the fuse blew .
Polarity is correct but I now think maybe I need a bigger fuse to power both the light bar and spotties at the same time .
Does anyone know if this is correct or have I got a problem using both sets of lights , main power wire to relay is fairly thick and is yellow , which I've seen lots of the same kit around .
Will see what happens if I disconnect one or both spotties I suppose that could confirm my theory .
