MG Car Repair: Hazard warning fuse, amp fuse, amp fuses

Question
Greetings,

I have a 1972 MGB.  The hazards are not working.  I found a replacement relay at local parts store.  It is a Tridon EL12 hazard flasher.  I installed this flasher.  I found an inline hazard fuse blown.  The fuse I pulled out was a 35 amp fuse.  This seems a little excessively sized.  I was wondering what is the proper size fuse?

Thanks,

James

Answer
James, the fuse was to protect the wiring harness not the flasher so a 35 amp will work fine because any short in any wire on an MG (other than radio) will blow a 35 amp fuse before melting any wire. The large brown wires should have 50 amp fuses so as not to blow a fuse to often. Keep in mind that a flasher has many bulbs to power and if you put in a low amp fuse it will blow when left on for any time like a flasher would be. So don't use anything less than a 35a fuse.
