Voltage issues: MHD/Dash reading low, but multimeter reads normal?
I tested at the battery, at the alternator (grounded to the alternator housing), and at the aux power under the hood. I get 14.7v all around.
When i read mhd codes or check in-dash voltage (menu 9), I get a reading of 13.1-13.6 How do i troubleshoot this? Not sure which wires it could be edit: IBS is unplugged to rule that out Last edited by tofu?; 09-03-2024 at 02:20 PM.. |
