FUSES !!!! thats wot wires are for !!!!!, without wires you can't let the smoke out !!!!!
There we are, full circle !
Getting back to reality, I have spent the last 2 days re-buiding my BMW motorbike in-fuel tank wiring and plumbing, what a royal PITA !!!!.
Give the astronomical price of spares (to pay all of those engineers) they do have some really crap materials in there.
I too do long for the days of carbs, petcocks, and simple switches.
Have a great weekend all.
