Short on fuses
Q Can a low/knackered battery lead to blown fuses? My 1996 Suzuki GSX-R750 SRAD is randomly popping the main 20A fuse. I started unplugging stuff; all other fuses, fuel pump, regulator, heated grips, etc, and it still did the same thing. I then removed the battery terminals and connected them to my booster pack and it instantly stopped. I removed the booster, put the battery leads back on and it’s still not blowing them. No amount of wire wiggling will make it do it on demand. Danny Brear, PS Facebook Group
A Ferret says: You have to love an intermittent electrical fault. One thing: it isn’t is the battery. Corrosion in switchgear can cause main fuses to blow. Also check for shorts in the alternator stator and the wires to the reg/rec.
