Lost my right side headlight high beam. I have another headlight bulb lying around (from PO) but have no idea if it's good or not. Since it's a bit of a bith to change bulbs on our little 914's on a maybe, I thought I'd ask if anyone knows how to test a unmounted headlight bulb. I have an ohm meter and I also have a continuity tester.
Thanks in advance David |

If one light works, it's not the switch or the Hi/Lo relay. Spin the fuse in the fuse holder . If the other lamp will light, there is power at one side of the fuse. The wire goes directly from the fuse to the lamp.

However my flashers still aren't working (IMG:style_emoticons/default/sad.gif) I've had my turn signal switch out lately (wiper switch woes) and that coincided with the flasher loss (evidently the right side higbeam was merely a coincendetial and un related problem). I've tried a new flasher relay and even swapped out a known to be good hazard switch....I still wonder at the column turn signal switch in reference to the loss of hazards. Are they or can they be related? |
