Turn signals not working, blowing fuse
I didn’t disconnect the radio, it was never connected.
Ok. It seemed like you had because you asked about it in post 51.
So as far as I (we) know, disconnecting the bulkhead was the first success in preventing the fuse from blowing.
Of course that might be a misunderstanding on my part.
I don’t think the reverse light switch does anything else. As far as I know, I don’t have a reverse indicator light.
The reverse light switch turns on the backup lights.
Your car is an automatic so there should not be reverse indicator inside. Might ther be a wire for that option? yes, might be.
The reason I asked you about the switch is this:
The reverse light switch and the neutral safety switch are combined into one unit.
The neutral safety switch works by grounding a wire coming from the starter relay whenever the gearshift is in P or N.
Think about that. Three wires connect the the transmission neutral safety/reverse light switch. One of those wires is grounded whenever the transmission is park or neutral. My understanding was the fuse did not open once you removed the connector with the reverse wire going to that switch.
I am an amateur, just learning all of this.
That's OK. I just thought its time we help you think this through rather than walk you through.
