testing

hi all the cold has taken is toll on my anus went out to start her an there was no life in her,
so i give her a push an she started yay just a flat battery so i leave her to run up a charge an get warm.
ok she has run for 10min or so ill turn her off an start her just to make sure its all good last thing i want was to push it home
oh there is no go ok ill test the battery with my v meter wow 17.6v with no loom on an is only a 12v battery
ok ill crank it as there is more charge than needed.
on firing the starter dropped to 3.6v
so i start to think my battery has got high resistance.
just to check i started her an tested her again the battery was sittin at 17v i then put everything on lights cb heater etc.
an she droped down to 12v then back up to 14v but after 5min my battery light come on the dash and park and oil light well they flickered give it some revs and they went out, drop them and after a min they come back on. so i test the battery an it was down to 10v and dropping. so i turned everything off an watched, it stopped at 7.5v for a bit then started dropping till it stalled.

hum help im no electrition but i do have a understanding of cars an there electrics and i understand this is not good and my guess is its the altenator.

yeah sounds like the alternater isnt charging properly, and it might have damaged your battery now to, try charging your battery up having another go, your battery should be at about 12.5v when fully charged, your charging circuit should be charging at about 13.5v to test your battery connect it up, take the 6 plugs out of the top of the battery (where you fill up with water) and turn the engine over, if one of the cells starts smoking (just abit of mist) one of your cells is f**ked and its game over for the battery

Yea sounds like the altinator is overcharging your battery. I have a couple of spares, if you need one send me a PM.

Yep, the regulator in the alternator is not regulating very well anymore and is frying your battery.

You may end up having to buy a new battery too but you might have got awaywith it!
