I'm having an issue with the running lights/associated circuity on my Elise causing fuse 16 to blow. It started two months back as maybe once a week, depending on tire inflation/heavy bumps, but has increased to whenever I press the top switch to turn them on.

Playing the game of trying things so far, I have searched the fourm a bit, and not had very much luck with finding a similar situation. I had the dealer go over it a bit to try and figure out why it could be doing that, which the mechanic thought switchpack was the most logical choice.

This is a 2005 Elise, Non-touring, non-sport pack, w/stage 2 lotus exhaust, and there is 71k miles on it (11k since I bought it and brought it to pittsburgh in April of this year).

As you can guess, there's a lot of bumps around here which I try to avoid. Some of these roads feel like death and sometimes not be avoided, ever drive a lotus on an old brick road?


The Symptoms are Fuse 16 blowing, which makes:
Front running lights,
Front side markers,
Rear side makers,
Rear running lights,
Gauge lights, (officer, i can't see how fast i'm going)
"Comfort"(fans/ac) center panel lights


I've done diagnosing of changing the switch pack module (dealer had one in stock, how about that?)
Unplugging rear/rear side lights at their harness plugs.

Luckily it is in a stable state (of the fuse blowing instantly upon pressing the switch to turn them on) for diagnosis. Not that I want to, but there are very helpful lotus owners around here with experience removing clams that have offered to help with such a task. I do have the wiring diagrams also, even highlighted from the switch pack out to ground.


Has anyone had any experience of similar issue? Maybe offer some troubleshooting advice? I would like to try to remedy this issue before I have to stop driving it and hide it for winter, which is unfortunately coming...

Thanks in advance!

I just had this happen. It was the license plate lights and wiring, burned to a crisp being just behind the muffler. I replaced the lights with units from a regular car parts store.

Let us know what you find.

Same thing happened to me. Found this post and went straight to the license plate lights. They were fried along with the wiring. I guess over time the exhaust heat melts the lights and wiring. Sure glad I found this post before pulling my hair out trying to track it down.
