Q: How Do You Test the Back-Up Light Switch on Honda Del Sol?
A: Before testing the back-up light switch, check the No. 15 10-amp fuse in the under-dash fuse/relay box. Put the shift lever in Reverse and turn the ignition switch to On. The back-up lights should go on. Turn off the ignition switch. If the back-up lights don't go on, check the back-up light bulbs in the tail light assembly. If the fuse and bulbs are both okay, locate the back-up light switch on top of the transaxle. The back-up light switch should have continuity with the shift lever in Reverse, but no continuity in any other gear. Trace the leads back to the electrical connector, unplug the connector and hook up an ohmmeter or continuity tester across the two terminals. With the shift lever in Reverse, there should be continuity; with the shifter in any other gear, there should be no continuity. If the switch fails this test, replace it. If the switch is OK, but the back-up lights aren't coming on, check for a poor ground in the circuit; if the grounds are good, look for opens in the circuits. To replace, unplug the back-up light switch electrical connector. Unscrew the back-up light switch. Discard the old washer. Using a new washer, install the new switch. Plug in the connector.
