Batt reading strange
fearlessgangsta posted a topic in Amplifiers / Head Units / Processors / Electrical
So I go to put my 3400 in after charging. It took it off the charger put it in the car check it with a DMM and reading 13.7v or so. So I hook everything up and start the truck. Voltage reads 15.1 then down to 14.8 on my stinger meter. I go to check my 3400 with a DMM and it reads 13.78v WTF. So I check my amp wires they read 14.8 WTF. So I check the 3400 again it still reads 13.78-13.79. Then I check my stock it's reading 14.8. My wires are ran like this Alt POS to POS on 3400 Alt POS to POS on stock POS from 3400 to POS on amp. My questions are. Is my amp wires reading 14.8 but my 3400 is reading 13.78? Is it because my 3400 is fully charged so it's not accepting the charge are something? Edit: So I went out and batt was resting at 13.17. Start the car it creeps up .1 by .1 to 13.30. I'm talking 13.17 1 sec later 13.20 1sec later 13.21ect. Ran over and checked stock and it was at 15.0 I then shut the car down. -
multi part electrical question; alt, fusing, cable
808kikdrum posted a topic in Amplifiers / Head Units / Processors / Electrical
I'll start with the electrical rundown- EA 220 amp alt., big 3 in 0ga, xs d2400 under hood, deka 100ah g31 agm in trunk, 1 pos. run 0ga between batts, all cable is ofc. Now for the questions, first the alt- i was told that the bolts holding the alt in place are all the ground you need but i feel like i should have a 0ga ground also. good idea? unnecessary? Now for some fusing-how should my pos. between batts be fused? i have an aq3500d.1 about to go in, do i need to fuse for its 400 amp rating?,fuse for the max current capacity of the cable at 15-20ft?, fuse for the max amt of amps that my alt and front batt can deliver? Are there any performance differences in anl vs. the multiple midi mini fuses? Now for the cable- how beneficial is a run/s of neg. between batts? Is it necessary to do a 2nd run of pos.? Seems to me the one run should be more than adequate to carry all the current the alt+front batt can give to the back batt/amps but i have certainly been wrong before. Thanks in advance for any and all help, to those tempted to tell me that u never fuse and its not necessary u can save both our time and not post, thx.
