Voltage Issues

[burko 6]

This may be something extremely simple and I may have just wasted my time by making this video, but I'm a little stumped as to what my problem is. I saved myself a lot of typing and you guys a lot of reading by just making a video. Give it a look and tell me what you think!

Took forever to upload the damn video.

I did not actually see you having a ground going from your batteries to your frame ???

Engine to frame ??? Or a upgraded ground from your cab to your frame ???

Which battery? When I was talking about the secondary battery I messed up and didn't actually film where it was grounded. But with the starting battery, it is grounded to the frame, and I have the engine block connected to the negative terminal on the battery as opposed to the chassis. And what do you mean cab to frame?

you can pm me and I can give you my number and talk if like ...

[Randal Johnson 544]

running a ground from your battery post to the engine will give you noise in your system ... not good ...

I seen where you was grounded to the body of the fender ... not the frame ...

[Randal Johnson 544]

Your cab / front cap / fender wells / etc ... have rubber post to prevent vibration ... hence not being good grounding points ...

I'm trying to help ...

Big 3

1. Battery + to Alt fused at the rating of the wire.

2. Ground Alt to frame

3. Ground Battery to Frame

I never seen a ground wire from Starting battery to Secondary battery. But if you ground both batteries to the frame you should be alright. Probably easier to run a ground wire from one battery to the other as opposed to running two wires to the frame. As long as one of the batteries is grounded to the frame that is.

So I should go from the engine to the chassis?

And about grounding to the fender.. Why would it still read correct voltage at the grounding point? Could this be causing my problem?

And unfortunately I'm upstairs directly above my mom's bedroom and she gets PISSED if a mouse scurries across the floor much less me talking. I'll shoot ya a pm and we can talk tomorrow if you're available.

Without a Frame ground as your starting point, you have no ground ...

Yes I think this could be your problem ... and a few other small things ...

yes, pm me and we can talk tomorrow ... this will be fine ... you have a AT&T phone ??

Hmm..

I have Verizon. Is that alright?

[Randal Johnson 544]

I've made a few minor changes since these pics ...

but I will explain everything to you in detail if you like tomorrow on the phone ...

like you said, too much to type ...

Got all new pics for the "Under the Hood" area of my truck on the last page of my build log ...

have you checked the voltage on both sides of the fuse? it could be a bad fuse that doesn't look blown. i've had that happen to me once or twice

Same here, had a guy bring his truck recently because his sub amp was going on and off then quit turning on but he had checked his fuse and it looked fine. Sure enough it did look just fine but a quick check with a DMM showed it was open. Being an AGU style fuse I set it on it's end and tapped it with my pocket knife and viola it worked again, the fuse element had came loose on one end. It's funny though, he's not gotten a new fuse yet, LOL.

question... have you calibrated your Stinger voltmeter? there is a little potentiometer to adjust and dial in the volt meter.. that could be it...

[Hotdog69 3]

He is getting the same reading on his dmm at the secondary battery as he is getting at the volt meter.

[burko 6]

Worked on it for 2 1/2 hours today and the only thing I managed to do is strip out the negative terminal on the starting battery and drip sweat all over the engine.

Oh, Shizz:

Well the wire between the two batteries isn't fused.. I checked the fuse going to the alternator and it's fine.

[Bl0ve1991 0]

This may be very irrelevant but when I was running a second battery in my car; once I would go down the road the voltage at the 2nd batt would drop down into th 12's. If I turn on the air/headlights to put strain on the car it would jump back up to the 14's. Very weird.

Think it could be something with the 2nd batt? Put the DMM on the positive wire that goes from your 1st batt to 2nd and use a different ground and see if it will read 14+.

Grounded good on the frame / engine / fenderwells ???

My wire was literally about a cm too short to ground at the place you recommended..

I have to either find another ground that would be as sufficient or order more wire. I'll take a better look tomorrow. I was so pissed/tired/drenched I couldn't even look at the truck.

Wish you was closer ... I have several 0g jumpers (about 1 to 3 ft long) collecting dust in my storage room ...

Go to your local welding supply shop ...
