Hello. D+ is for warning lamp. W is for rev counter if you have one fitted.
HI, Thanks for the info on the terminals. The alternator still won't charge the battery and this is the 2nd one that I've tried. I don't know what to try next.
Does the battery warning light stay on?
Yes it does.
There is the possibilty that because you may have wired it incorrectly that you may have damaged the new alternator.
