NewB here.
I am the original owner of my 3500 Dodge.
Bone stock, Cummins, 6 speed manual, 146K miles.
I have a problem with reverse lights not working.
I found a tread that included a schematic and a lot of good info.
But......here is where I am today.
I have 12 volts at my fuse panel for the BU lights.
I have a new 10A fuse.
I only have a few volts, it is floating, at the reverse lamp switch on the transmission.
I can hook a battery to the connector on the trans switch connector and get the BU lamps to light up.
I followed the harness from the trans back up to the back of the block where it joints to a large group of wires.
At this point I am lost and don't want to split the large wire harness apart.
Any Ideas, and Thanks in Advance.
