what to do if alternator wont charge at 14.5v?
hello forum. in my car (1992 audi 80) , the alternator, has a brand new voltage regulator, rated at 14.5v. i also have two batteries installed, isoalted with relay. the problem is, that the alternator, does not charge them at 14.5v. even with no load, (And only one battery) the voltage is max 13.9 ...., with the load, its aroudn 13.2 or so... i know the best option is just to replace the alternator, but for various reasons, i cant do it yet.
so my question is this: Do i need to worry?? i know that batteries want to be charged near 14.5v...
what can i do to increase the voltage? any internal mod in the alternator?? or could i use a high amp switching dc-dc converter?? thanks!
