How many amps is the fuse on the relay
80 amp? 30 amp
reason i ask is because i just blew a 80 amp fuse,car was running normal,i changed all glow plugs and the only thinng i notice could be causing the problem may be that one of the harness pieces that attaches to the gp via the 10mm bolt is bent and touching itself,could this cause it to short??
thanks all

What year/model car are you talking about?
