many alternators charge at 13v.. my singer did too the only difference is that it held 13v with a load.. check connections and amp gain.. on my expo i would drop to 11v with a mechman that does 240a at idle set at 13.8v. set the gains with DD-1 and it was fixed..

During the summers in PHX. My Powermaster used would drop to 13.7 when it was 105+ out. Winter it would charge at 14.6. both numbers are while driving

13.6-13.8 yes. Less than that, no. No vehicle on a standard 12v electrical system will charge that low. the only reason for voltage to read lower than that all of the time is the alternator isn't charging at the voltage it should be.

Yea i noticed other ppls 12v systems would be at 13.8 or even 14

510? are you in the bayarea?

yea you probably have a loose connection somewhere or a bad alt... with your voltmeter ground your negative lead (battery, or frame of car, bare metal) and with your positive lead directly to your positive output stud in the alternator while the car is ruining and that will narrow down whats going on, then post results here..

guys i found his alt it has to charge at 14.4..

yes but you can rule the alternator is bad.. check connections.. check every wire like grounds and even the back plug on the alternators.. all that can make it not operate properly

i haent run my singer during winter.. they charge at 14.1 and drop to 13.8 once hot.. im sure it will jump higher during winter

Ive asked different ppl the question of if i should ground the alternator to the chassis and ive got different answers, so would it matter if i didnt ground it or not

you shouldnt talk before knowing.. i have ran DC alts.. and there is a person i got one from that he can prove i have DC alts. im also not new to alternators.. i have swapped in and wired alts to my cars even before being a member in this forum.. the ones you have had are not the one the OP has.. i know the ones i had have ran at 15.2 and drop to 14.8 but not ecm controlled. not all alternators and vehicles are the same. also not all DMM are accurate.. i have a high end one that reads one thing and a $20 one and the readings are way off.. my high dollar one matches with the smd meter and xs power meter the cheapy one matches with none

go ahead and ask kevin from cnf who got his a DC alternator when he got 8 xs power d3100 from him.. then go ask broke audio who bought his dc power alternators

illl take this to the pm's miguiel....

i dont what to clogged up your thread op... im in hayward so hit me up if you want me to check it out , ill be sure to take my harbor freight DM, fluke RMS DM, fluke clamp, amm-1.
