They rest at about 14. 56 volts. if not used for weeks itll drop to 12.56// . i was thinking a switch inline of the alt sence wire maybe shutting off the power to alts at night wont warm them . and the whine is really not loud . i can only here it when volume is off or barley on.. i just dont like the alts getting warm when not running.doesnt seem good for them. thanks.

well its easily read i wanted to put all facts so id get a good answer... if u cant read it i guess you cant help..oh im partially blind to so my spelling isnt always on..

hello all been awhile .. i have a question about alts i have 3 alts 2 for system the other powers the van. its a mecury/toyota van. yes mecury /toyota they called it mercury villager but made by toyota. im using chevy small case alts..they charge fine i only use the one wire off of them the sence wire. i dont use the dummy light wire.. now i was told that buy doing this alt.it would not draw power with sence wire connected to audio batterys . ive had many people argue the fact it does not draw power.. ook well this eve i was standing by my van and could here a slight wine.. i opened hood and related it to the alt sound was clearly from alt . second the alt is warm just setting there i know this cant be rite alt should not be warm when it hasnt ran all dayPlus it created a slight noise threw my front stage speakers which dont run off of the same alts, runs off van power front stage if i un hook the sence wire to audio batts it stops the speaker nosise. its a gm alt battery wire and 2 wires on top plug in. one is grey and the other if i remember rite was white.. the alts are for a chevy cavalier but bolted to my van nicely without much fabrication.. so my questions are why does alt whine when not being used and why does it get warm when setting, no driving.. have i got a wire messed up some wheres ive checked and re checked. any help greatly appreciated. thank you.

just installed a brand new chevy alt on my mecury van , its chargeing but not fully i ran over my DMM so i cant test it till tomorrow.. theres 2 wires on the alt one is grey the other is white.. 3rd wire is the big red battery wire.. the gray im told is to battery power and white is a exciter wire but am told you dont have to use this white wire because at 1200 rpm itll turn on.. so a quick test and it was chargeing but i was using a test light for the time being and it was lit but not as bright as the vans own alt when i hooked it to van alt it was bright.. not as bright with second chevy alt .. any one have a clue why its not fully chargeing or am i missing something.. its a small case gm alt originally for a chevy cavalier.. bolted on fine.. this alt will be runnning only my amps battery bank.. . maybe theres a good wiring man here,, ps im told to just hook the grey wire to the battery but after car is off theres still power to alt is this not correct and something about using a bulb as a resistor on white wire to excite the alt hows that done.. thanks so much all..
