voltage issue

[hove 15]

this weekend i worked on the car some. i installed my voltmeter, when i installed it it said "LO" figured cuz the car wasent on well i was working on it and the batt drained some. so i hooked up a charger and let it charge well i finnished wireing my active front stage and my sax100.4. when i was done i turned the car on and i had nothing playing at all. volt meter went up to 11volts, i drove around and the highest it goes is 11.4. i have the big 3 done. i have an optima g35 under the hood 720 cold cranking amps. when i stop at a red light it drops down back to "LO" witch is under 10 volts.

i have an 06 envoy. when i was running my wires and installing everything i noticed the previous owner had a small system possibly cuz there was pre drilled grounds with wire still in the but cut off. lol

maybe the ruined the ALT? what do you guys think?

thanks!

jay-cee helped me with some diffrent ideas but still nothing.

i think i know

you have a stinger voltmeter.. i just checked your build log

but did you adjust the voltmeter? when you take off the cover you'll see a little screw. this is to adjust to voltmeter's reading due to the resistance in the wires that are hooked up to the power source.

i did not know about that at all lol maybe reading the manuel would help but you know how that goes with guys lol.

i am about to go outside and check that and hopefully thats the issue lol

it will be the issue.

here's the process:

-turn car on

-put volume on zero

-use your DMM to measure the voltage at the location in which your voltmeter is wired up to

-adjust that screw that i mentioned to match the voltage read by the DMM

thanks mbarb! i feel kinda stupid it was that easy. i was all worried about finding money to fix this issue lol

lol no problem man!

i'm glad it was only that and not something big for you

So it ended up being the volt meter that was giving you a low reading?

i hope so jay-cee, as soon as i get off of work i am going to do what he said for me to do and hope it works!!!

lol the same thing happened to me when i installed my stinger voltmeter! and for some reason the cover fell off and i was like hey check out this screw in here what happens when i turn it!

turns out i just got lucky and stumbled across it! lol!

yeah that should fix it, take front cover off and turn the screw clockwise i believe, match your voltage from the dmm and BAM all done

did that end up being the problem?

..must have been since u didn't say anything again

Thanks again!
