Is there a proper way to raise the MG to replace the backup sensor? Ramps or jack? I do not want to stress the body connections to the metal frame. I don’t believe there is way to access the sensor from the inside. MG has an air cooled VW engine, if that has any affect on the situation.<span class=”Apple-converted-space”> </span>
Thanks for reply. I am assuming it is the switch because the bulb is good. Looks like a tough place to reach and change the switch from the bottom. Wonder if the switch be reached from the inside. Car in storage now and will look inside next time I check the car and follow the wires. Basically a push-buttton configuration type switch. If I cannot locate a replacement, I may be able to improvise.
Check the connections before replacing the switch. Grounds are gremlins on TDrs.
Also make sure the car is actually shifted into reverse. When I was putting together my Spyder the backup light gave me a heart attack when it wouldn’t work despite my shifting it into reverse to test. I checked the light, the wires, connections and even the switch itself; no joy. I thought reverse gear might be fouled up inside the transaxle….
Then I rolled the car in gear and watched the flywheel. Turns out what I’d thought was solid reverse was just second gear again, because my home-made shifter linkage bracket (it’s a cable shifter; everything is backwards on the Spyder compared to a Bug or TDr) was allowing a tiny bit of deflection.
