Greetings all,
Please excuse the first of what will probably be a small stream of posts as I'm finally with the 914 for a few days so I'm working through a few things. First item: I changed out the bulbs in my pilot driving lights that are in the stock positions - put there by a PO or probably Brad Mayeur. I changed them to standard H3 55w lamps but went to a little more blue color to match the LED headlights I have installed along with the spoke works relay to deal with rapid flash and other side effects of the LEDs. The fog light fuse - 3rd from the right - gets pretty hot and will eventually melt but does not blow. Could it be as simple as high resistance at the fuse location in the fuse box? It appears - through trouble shooting - that it only happens when the drivers fog light is installed. if it's not and only the passenger lamp is installed, no issue. Different lamps show the same behavior. Thanks for the input! |

Are the pilot lights rated for 55W? The stock foglights are only rated at 35W so the extra 20W might be too much for the fuse and old wiring?

(IMG:style_emoticons/default/agree.gif) If you up the wattage on the headlights or the fog lights, you need to add a relay to the circuit. There is a kit available for the headlights on a 911, but all you have to do is add a wire and fuse back to the battery to power it if you use it on a 914. Zim's headlight kit. (IMG:http://www.914world.com/bbs2/uploads_offsite/www.allzim.com-1143-1572009216.1.jpeg) You can do something similar for the fog lights. Or go to LED bulbs. They actually cut the wattage, and get MUCH brighter. Now you can be as annoying as the new cars. |
