voltage no matching to battery bank(alternator not chargin?)


Recommended Posts

hey guys!

i was having issue and i was thinking it was my mechman alt not giving me any output, but when i finally had bought a new ddm hoping it wasnt my alt and my cheap ddm that wasnt telling me the correct output, so i got a new fluke 115 and my front battery was 14.2-14.3 which is fine since i was seeing 13's with no load, but i realized that wasnt an issue whats so ever it was my back d3100s in my trunk there not getting a charge what so ever with the car off it was 12.8 and with the car on it was also 12.8 why could that be??? im confused on that

check your grounds for the back battery make sure where ever them batteries are grounded to are tight and clean so they have a good connection.
