Here's one for you. Just sorted a 1960 250 crusader. Took me ages to get it started and when it did start the ammeter showed a total discharge. I'm thinking the regulator but I'm open to suggestions. Any ideas out there?
With the engine not running the ammeter shows the usual discharge when the lights are switched on.
Cheers

Check your wiring sounds like the rectifier output is reversed.

Thanks revband, I'll check it tomorrow.

IF the rectifier was 'accidentally' reversed, (Pos Earth? - Neg Earth?) and not the battery as well, there will be Smoke being generated from the wiring.


Check the wiring terminals at the light switch, in particular at terminals 7 & 10, the two alternator feeds Green+black and Brown+white.


The old Lucas switches dont last for ever, and the wiring terminal securing screws do vibrate out...

Thanks for the help guys.. After stripping everything down and tracing all the wires. Discovered that the wire colours to the battery ware reversed so the whole system was reversed. Swooped the wires and everything was fine!! What a plonker!!!

Dutto, it may interest you to know there is a Yahoo Group especially for Crusader fans, find us at https://groups.yahoo.com/neo/groups/Cru ... group/info

Reversed battery leads or reversed rectifier leads would have much the same effect, but I would have expected that the ammeter would have shown a charge rather than a discharge. Thanks for owning up

Reversed battery leads can and will kill the rectifier and/or the battery.

(Don't) try that with a Boyer power box, the capacitor doesn't half go with a bang... I don't think a 1960 Crusader would have any regulator if it's still on the original 6V system, just the rectifier.

Perhaps I should clarify, I would have expected the ammeter to show a charge when the lights were turned on.
