hello all
95 944T
this car has 13.8 volts at the alternator but it measures 12.8 volts at battery with accesories off.
(my 94 945T has 14.1 at alternator and 13.9 at battery.) why is the 94 dropping one volt from alt to battery?
i have cleaned engine block ground and other smaller blue ground, cleaned the battery terminals. cleaned every +12 wire at the battery.
also replaced a poor fusible link to the elect radiator fan that looked to be overheated and the insulation was falling off the wire. replaced the wire also.
i removed and cleaned the connections at the starter also.
i swapped in my good battery from my 94 a couple weeks ago, now its getting weak like the previous battery in the problem car.
how much voltage drop is acceptable?
the alt is old but putting out decent voltage, it has a brand new voltage regulator volvo brand.
i am stumped.
i guess its must be in the wiring but open to anyone with more experience on this subject.
thanks
mike
