HI GUYS DID MY MTHLY START ON BLUE AND WOULDNT START ....BATTERY / PETROL ALL GOOD ...KEPT CRANKIN IT ..AND THEN FROM UNDER THE DASH SHES SMOKIN ...OUT OF CAR DISCONNECT BATTERY WIRES TO ONE OF THE FUSES MELTED IN BEHIND FUSE BOX ALSO ON THE REGULTOR (BLACK BOX) FEW MELT OUTS WAS JUST GETTIN IT READY FOR REGO ...AH SHIT .....WILL TAKE A FEW PICS ..MAYBEE NEEDS A NEW HARNESS ..BUT WHY DID IT OVVERHEAT ?? WAS THE FUSE TOO HEAVY WILL CHECK ALL IS GOOD THE CAR DIDNT CATCH FIRE WILL KEEP IN TOUCH CHEERS DAVO

not entirely sure why it would have done it, maybe too much resistance in the connections (dirty connections)?

Glad you didnt loose the car to a fire, maybe some one with more knowledge could help?

Let a cat loose in the car to check for rats just incase if it has been sitting apparently they like eating wiring looms??

hi guys pulled out the fuse box t wires joined one white (frazelled )the other a black /yellow stripe ..which clip into the fuse panel ...where the black one goes tried checking the wiring diagram ??? pretty small the white wire comes out at the regalator ist connection on rhs its frazelled so obvious according to farmer perhaps the regs r/s took it off the points were wide open something going on there i have another regulator out of a 67 its a bit different looking has same amount of connections ....mmmmmmmmmmmmmmmmmmmshould i run a wire and try ..and have bucket of water and a beer handy wanyone experienced this bar b que wiring ???

Hey Davo

That black wire off of the fuse box goes back directly to the relay & starter solenoid, on the same terminal as the hot side of the battery is on, so this would take some amperage during starting.

electrical problems can be so dodgy ...

good luck dude

Davo those white wires go from the alt to the reg if you unrap that section it will seperate from the loom i think you will fing the light white will be your charge light and the fat black will be your power supply to the fuse box.
You will need to check other wires bundled in the loom to confirm they are not melted together. I run a fuseable link from the power supply to the fuse box to prevent this. The problem is the wire from the battery or starter solinoid is always live and it has no weak link until it leaves the fuse box, a fuseable link looks like wire so it will not effect the standard look that you are trying to achieve. They come in different colours for the right amps get some advise from a auto electician as i have estimated what amps i have used.
You will see in the photo above the 2 on the date this wire is 2 inches of fusable link in the event that the main power supply to the fuse box fails this 2 inch piece of wire should burn out before any other damage can occur. Your car may be a little different as i cant remember the set up as i think it was a later engine set up than the teardrop But it just needs to go as close as you can to the power supply.

hi guys thanks so for alll your comments .had the sparky call today reckons the wires will have to be checked from a-b where apparent damage reckons also put on an updated regulator and alternator ..he said its a big job ....how big approx $$$$$ wait for it $600 ..i will get back to you ....maybee .....anyway i have stripped of the insulation tape from a-b only one damaged wire the white culprit which is burnt ...the next thing is what do you suggest i put in for a regulator and matching alternator ..sparky said a later model car would suit ..he didnt tell me which one ...so come on guys .i have been draining the farmer and orphanage so far anyone else had experience on the update cheers davo some shots oh yea the regulator points were totally wide opened ha said that wouldnt have helped ...

sorry ....

Maybe have a look at a local wrecking yard to see what car has an alternator that looks close to fitting?
correct me if im wrong but are there alternators now with internal regulators, and some with external? Sorry auto electrical is not one of my strong points!

cheers mate not mine either look at what ive done theres bloody wire everywhere ...believe it or not the car is running the sparky put the wires back on and zooommmmmmmmmmmmmmmmm no hang on that a mazda .......maybee more of a purring sound (yea) like a 40 plus year old one ...will keep in touch and see what we can hear out of the forum cheers davo

$600 seems a heck of a lot.
i have no idea what the fault actually is, but those regulators and alternators are pretty reliable normally. But it might be faulty and I would just replace it with a used one and fit new wire. With a fuse or fusable link perhaps at the battery end. Maybe another Bellett Alt. also, to make sure.
