running lights and back-up lights not working. 2001 E350 based shuttle bus
JA: How old is your battery? When was the last tune up?
Customer: Battery age unknown. Cranks very strong however. Plugs and boots replaced app 600 miles ago
JA: Tell me a bit more about what's going on so he can help you best.
Customer: Turn signal and brake
lights (two on each side) work fine. No tail lights when headlights
are on. Also no licsense light
JA: Are you hoping to fix this yourself?
Customer: Yes. Electrical gremlins can be very time consuming and expensive
JA: Great! What have you tried so far?
Customer: Ive checked the ground at the lights because I figured that was the only thing in common with the tail and reverse lights. The ground wires show connection to chassis ground with meter
JA: Is there anything else the Ford Mechanic should be aware of about your Ford?
Customer: I have no manual to show me fuse layout. There seem to be many different ones on the net
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Ford Mechanic about your situation and then connect you two.
