one for the sparky's.
the standard set up and basic diagams only use one fuse,between the
battery and ignition but a short in the brake light or any cicuit will kill the engine.
so is it ok to put fuses in all the live wires ?
wondering if the tympanium unit needs to be pemanantly live too :confused:

while fuses are a good thing they can also be a bad thing, The more connections you have in a system the more failures are likely. Many times when things shut off, it's the connections at the fuse holder.
I usually fuse the lighting system only because it is the most common source of all shorts, and I don't bother fusing the ignition because when it shorts, it just shuts off.

Andy: a friend told me this...

"okay, let's talk about watts. this stuff will help you choose fuse/breaker sizes and wire gauge for your lights.

- watts = volts x amps, amps = watts / volts

so if you have a 90W (watt) high beam on a 12 volt system, the current (amps) it will eat is 90W / 12V = 7.5 amps. but light bulbs draw lots more current when first turned on, so add 3 amps for good luck, giving 10.5 amps."



cheers ::)
