Can't Find Engine Fuses

7999 Views 8 Replies 5 Participants Last post by  komiko
I hooked my battery up backwards, threw a code. Reset it and still have a problem. Searched the issue and I can't believe so many others have done the same thing, makes me feel a little better.

It appears that I have most likely blown a fuse but I can't find my engine compartment fuses. I have the Lotus SC and I believe it was installed by a Lotus dealer.

Does anyone know where they moved the fuse blocks? It is not behind the seats. I lifted a pic posted by dspecgsx (thank you) posted below, my view is the second pic.

Any ideas? MY 2005.

Thanks. Just spent 20 minutes with a good light. It APPEARS the blocks were moved lower on the firewall below the supercharger. I can't get my hands in there from the top.

Starting clam hinge install tomorrow. Hopefully I can reach it from the bottom and move them somewhere more appropriate. I can't believe this was a Lotus standard install.
I hooked my battery up backwards
This has happened before, I believe it ended up being a fried ECU... :( I wish you luck
I think the ECU is fine With the battery hookup I immediately stopped with the spark. She starts and runs fine other than rev limiter kicks in at 6,000 rpm. I found several posts with the same symptoms from the same bonehead move. The fuse fixed the problem.

I do believe I fried my amp though, but haven't bothered checking fuses there yet.
Got to both of the fuse blocks, freed them and temporarily moved them. The ECU fuse (R4) was blown and all other were visually inspected and tested as good. Replacing R4 did not correct the problem though - no change.

I read several threads on the same issue with R6 being the problem. So, I replaced the good R6 with a new R6 as other members have reported and problem was solved.

I don't understand it. The old fuse looked good and tested good.... Thank goodness for the forums.

Oh, and the clam hinge is pretty damn cool!!!!
good news. good job.
Sweet! Clam Hinge ROCKS.
