I can't pretend to be an expert on electrics, especially on a '62. But, it sounds like a dodgy "earth"? Probably worth going over all the connections in the indicator wiring circuit and cleaning them all up?

Re: front indicator problem can you help?


Yes, as Kentvette says this is likely to be an earthing fault.

The first places I'd look are close to lamps which are flashing dimly, especially anything with a "twin filament" bulb.

If you think about it, a twin filament bulb has 3 contacts. For instance a twin filament tail lamp has,
* live for 21 watt filament
* live for 5 watt filament
* ground

So if the bulb's ground contact gets disconnected from the chassis (particularly likely on a fibreglass car!) the current will try to escape through the other filament and off around your wiring until it finds an earth elsewhere. It's because the filaments act as resistors in series with each other that the lamps only illuminate dimly. The same can happen with multiple single filament bulbs depending on the particular car's wiring.

A voltmeter can help you find the fault because if you test at the "live" side of a bulb that's flashing dimly and see a full 12v you know the problem's in the other direction. Similarly if you see low voltage on both sides of a bulb you know you're "somewhere in the middle" and not at the site of the fault.

Good luck!

A nice simple and logical explanation - thanks (of behalf of the potentially confused)

Agree Ross, a great explanation! I'm sure there are many like me who know what happens, but not why! Rolling Eyes Very Happy

Thanks!

Another thing to look out for is that the earth circuits often join together in places via a connector. These connectors corrode internally and so whilst your particular earth circuit may be physically connected at the light fitting and likewise at the earthing point, the corrosion will break the circuit en route. A good jewellers file will help to clean the internal connections within the connector "box".
