Replace dynamo to alternator

[ronnie]

Hi all , mines is a 68 minor 1000 positive earth. Any advice on the changing to an alternator Will it fit straight on to the engine block or mods needed and the wiring ???

Do you actually need an alternator? A good dynamo on a standard car is quite sufficient, even in winter.

Hi , can't say I really need an alternator I just thought it would be a decent upgrade , thanks for the wiring diagram louise

Well, the Minor's electrics are pretty limited and don't draw much current; if you struggle in winter with wipers, heater and lights on all at once first check dyno brushes and then perhaps upgrade.

I have to say I never yet charged a battery on a standard Minor because the dynamo wasn't charging it fully.

If the dynamo is working - leave well alone.......

change to an alternator is very easy and well worth while,if you do a lot of short runs and winter driving,and want piece of mind all year round,second thing I did after radials,however I do have a heated rear window plus radio and like to run on sidelights.
one year and no problems ,ya pays ya money and takes ya choice ,good luck

First move would be to change to -ve earth........ and by all means get an alternator (or two) in stock by roaming the local scrappies...........
