over charging

[swedge]

well had to get a raplacement alternator for my c14se, my mate had one but it was slightly larger than mine not sure what its from

anyway i fitted it and its reading 13-14v idle and going up to 19 at full rev :(

is this just because its a larger alternator? im guessing ill need the same one as my old?

it should still charge at ~14.4, but higher amperage capable. Have the same issue with mine atm and keep meaning to get a thread up to see if its new alt time or I can just change the charge relay, which I believe is the little black box on the alternator.

i can get another alternator easier enough just wondered if it could be the wiring or something

plus i dont really wanna drive it like that lol

Will be the alt regulator on the back, If you can find the bits, You can change them. Not such a common thing these days though unless you use, used stuff.

Your regulator is buggered.

You're also probably feeding the battery with AC rather than DC. That will sh*g the battery pronto.

Don't run it until you get it fixed IMHO.

yeah im not running it only took it round the corner to see if it would settle but it didnt

spot on, mine went and was pumpin 26v into my battery, which on a 3 min drive @ about 30 swelled up and started to vibrate :(

They can gas big time and that could lead to *BANG* as the hydrogen says pop!
Plus the acid makes a mess of the under-bonnet paintwork.
