if its been chargeing at 15 volts it will boil your battery.. even if it doesn't leak it will belch out a cloud of acidic steam which can condence and puddle.

Cheers both

Gave the battery (Optima Red Top) a good charge yesterday, was only at 80%, it’s full now. Was going to reconnect and do some testing later. Don’t know much about this type of battery, but guessing it won’t have done any permanent damage?

This would explain the small puddle!

if you run a lead from battery negative to the body of the regulator and the voltage drops back to below 14.?? say 14.3 or so, jump lead would do

its an earthing problem. battery negative or the screws that hold the regualtor onto the car

if its a mechanical regaulator and this makes no difference it needs to be reset by bending stuff inside...check manual...
if its electronic, and sorting the earthing has no impact hard to say if its regulator or alternator problem...probably the fomer.


measure voltage at the battery... voltage at alternator output will be a smidge higher due to resistance in the path between it and the battery, and its battery voltage that counts.

regulator is sampling battery voltage in order to decide how hard it switches on the alternator in order to maintain it at 14.3 (well less than 15) when chargeing. The i am full but not boilimg over voltage level achived when no more charge current can be pushed in.

its comparing what it thinks is earth voltage, what it sees as 0V, with what it measures as the battery voltaage when battery is being charged...
if the case is not earthedwell, the 0 volts it sees will be higher than the true 0 volts at the negative post of battery, and you overcharge. regulator has false frame of reference.

look for rust at mountings and green verdigris on brass/copper based connectors

D’oh! #-o What a tool I am!

Was just reading through all that and thinking at least I don’t have to worry about the carb anymore and then I looked again at this photo…

When I came to put it back on the car, I only saw the big square rubberised gasket that was left sitting on the intake, so gamely replaced it with the papery one that matched it for size from the kit. Dropped the carb on, jobs a sausage.

Looked again at the photo of the kitchen table devastation and realised I’ve forgotten to replace the 4 holed gasket that goes on the base plate… 8-[ :roll: :clown:

Back off she comes in the morning, then… :roll:

We've all been there! At least its an easy fix, I could give you a few instances of a forehead slapping moment that were a lot more work than that to sort out...

:lol: Just annoying! Ah well, the correct jets have turned up now, so at least i can do it all in one go tomorrow. Hadn’t considered that it would need two gaskets on the same hole, to be honest! No leaks to report.

Will nip up the motor factors in the morning and see if they’ve got a vacuum gauge whilst I’m at it.

In the meantime, most of tomorrow will be trying to find out why it’s doing it’s best to blow my battery up. :-k

If it turns out it needs something replacing I'd seriously consider stepping into the modern world and fitting a Denso Alternator, rock solid reliable and no external regulator, it's like stepping up from a dynamo I tell ya!

Interesting, Blue. :-k Tell me more! I’m all for simplifying things and taking out weak points. Is it a plug and play job, or much Bananarama!-arsing about rerouting stuff?

With the right brackets it’s a straight bolt in, just needs a couple of wires sorting, easier than a carb rebuild! Mancini do a kit,
http://www.manciniracing.com/maenalkit.html They used to do a conversation using the tiny 45 amp Denso which Is what I use but they seem to have phased that out.

I see why you say “if anything needs replacing”. That’s an expensive set of brackets!

It includes the alternator, but if you can fix what you have for chips you’d do it.

:D Ah, that’s better! It read as if it was just the brackets! :lol:

It doesn’t read well but the brackets are about 50 odd bucks…

Will certainly consider that if I need replacement parts, dependent on shipping.

Not long had a new voltage regulator, so hoping maybe a simple wiring issue.

If I get up early enough, I may set about moving the battery to the front, which would make access all the easier.
