I have had a few electrical issues with my 2006 RHD (UK) roadster that I've lived with for longer than I ought. As a mechanical engineer, I am ashmedly pathetic with anything electrical/electronic.
1. I have a constant battery drain (noting a significant flash - much more than the norm, when connecting the battery), which results in a flat battery if the car is not used for a week or so. I am suspicious of an afterfit reversing camera, but this is only based on 'gut'.I have written a procedure to measure and track down how much current is flowing and where it is flowing to - you can simply do the tests and find the culprit, or keep guessing and guessing - most prefer to just keep guessing. I will try to find my post here on the forum for you.
2. My young son was messing around with the cigar lighter some time ago, which caused the socket to no-longer function. Having checked fuses, there is no failed fuse as far as I can see. In all cars, as far as I know, there is one fuse that powers the lighter and glove box light. It is powered only with the key "ON", unless you do my mod. It's location varies but it's a 15 amp in the box under the engine hood. The owner's manual AND the card on the bottom of the fuse box lid will tell you which one it is. If the glove box light comes on, then the socket itself or the lighter is bad.
3. Probably more significant, the seat motors do not function. Bizarely they 'spark to life' every so often. This means that I can't swap cars with my wife, as her feet don't reach the pedals! Again, no failed fuse as far as I'm aware. If both seats refuse to work, then work for awhile, then quite again, you need a new power seat relay.
4. The Infinity stereo unit occasionally goes on strike, and then remarkably comes to life again. Sometimes it works, but is not controlable, which can be embarrasing if the volume was previously set high for a heavy rock blast, when picking up the mother-in-law! YOu can chase this if you want to, but the OEM unit was always crap. I'd replace it with a modern head unit, the Marine ones made by Kenwood/JVC are a good color match. It can be the amplifier but it's usually the head unit.

I am happy to invest in an expert to fix these issues, if this is what's needed. I live in UK midlands, if there are any recommendations for an auto-electrition that can be recommended. Ideally a mobile expert.

I have struggled to obtain a wiring diagram for the car (RHD, as mentioned) that represents the under-bonnet fuse box. If anyone can point me to something that might be applicable, it would be appreciated. The service manuals here on the forum all have diagrams that are pretty close. Some fuse locations and functions changes over the production run of the car, but most didn't.

Any guidance would be appreciated!
