Evening all!
24FFR - fantastic electrical system. You can convert to 12V. However, I have grown to like the robustness of the 24V system. The screened electrics have the effect of making them water tight and reliable.
The higher voltage means current is reduced and this increases the life of the wiring loom.
The ingition system is 12V. the black box on the rocket cover is a resistor which drops the voltage to the dizzy.
Parts which are 24Volt as far as I know which would ahve to be changed:
- windscreen pump
- windcreen wiper motor
- starter motor
- alternator
- heater fan
- light bulbs
The 24V system also means a very crisp start on cold mornings.
Down side is you have to buy 2 batteries instead of just 1.
The sparkplugs are quite hard to get hold of. Someone on this forum directed me to Ebay where I picked up some relatively cheap new ones. Other sources are available and I admit that £7.50+VAt for a sparkplug is a bit steep. Most people change the dizzy, plug leads and plugs to a more 'conventional' arrangement and it is easily done.
What I do like is that the MOD plug leads have copper cores - like old fashioned ones. Modern plug leads are carbon fibre and less robust IMHO.
24 volt bulbs are easy enough to get hold of from commercial vehicle suppliers.
The really 'iffy' part of the whole rig is the voltage regulator which lives in a black box about 8 inches square located behind passenger seat. These are as rare as hens teeth to find. I have a garage full of dead units which need repairing - any ideas?
If you decide to change to 12V, i'd be interested in aqcuiring the voltage regulator, distributer, starter motor and alternator.
There will come a time when even I will have to convert the electrics to 12V.
I have wiring diagrams and an MOD user handbook for 24V FFR - the appendix gives very detailed instructions for squaddies for destroying the vehicle to prevent enemy use.
