24 Volt Update? 1980 Lightweight FFR

Hi folks,

Having some issues with a 24 volt FFR on the charging front - basically it doesn't
I've got my hands on a spare generator and box which were working prior to removal from another FFR.
Idea being, just do a straight forward swap over and see what happens, probably the easiest option.
If this doesn't sort out the issue, how straight forward is it to replace the military generator with a modern civilian type and associated items for a working and reliable charging system?
Ideally keep everything as 24 volts.
If anyone has done this successfully, any information would be appreciated.

Cheers in advance,

Al

Reasonably sure that the alternator is a straight swap. Then change bulbs, battery arrangement and possibly indicator relay.


But really you should wait for a grown up to answer.

Conceivably, a lorry/truck alternator would be 24v and might be the basis of a solution? Ffr alternators do come up on ebay tho, for not too much sometimes.

Thanks for the help guys -
I'm going to go down the route of a modern alternator and just by-pass all the FFR kit.
Just got to find a suitable replacement that will fit though.

Cheers,

Al

Sorted out the issue all by myself
Checked the generator panel for anything obvious internally - nothing.
Removed the "return" wiring and it seemed to be a little loose, out pops a brass locking ring that keeps the screw connection attached to the wiring casing and screws to the generator panel - refit the locking ring and screw back in place - nice and solid with no play.
Check the voltage at the batteries - 28.2 to 29.2 volts over a 4 hour period with lights, without lights etc. No real fluctuations noted, so I think it's sorted out :amen:

Cheers,

Al

Seems to have been a competent fix as I've had no issues since
This morning fitted a digital volt meter (purists?) purely for reference and peace of mind, also a couple of of cigarette lighter power supplies - all three in the blanked panel to the left of the main instrument panel.
No more guessing and a fully charged phone for when it inevitably "dies".
