I note from the dual battery wiring diagram that the connection from the system battery to the BCM is unfused so that if there is a short to ground (due to moisture) in the BCM then there is nothing to stop the max battery current flowing to the BCM - so I agree with the rational for your mod as in the event of a fault it will likely prevent further damage to the vehicle. Nice job.

Hi, well I was all set to do the mod this weekend after flying home from work, my neighbour knocked this evening to say she thought she saw smoke at the back of my SL. Guess what...... Luckily I caught it before the car caught fire but the wiring, module and some carpet has melted. Obviously the car is now totaled, but I want to get the car off the road and in to my garage. How do I get the car out of park, and the steering lock off? Any clues?

Great job! You should try to get the car as original as possible - grille, removal of boot spoiler, etc. These are future classics! Give the steering wheel a go, its an easy job and will make the driving experience so much better.

Thanks, you are the first person to ever say remove the spoiler, the grille though I have had a few people say no but majority like it. The steering wheel I am looking at replacing with the wood combo, but may just dye if I can find the right colour

Did you generate this thoughtful mod yourself? I haven’t seen it anywhere else. I would think the fuses could be even smaller as the box doesn’t require much current to operate. Parts ordered for my 2005. THANKS
@GrooveOn7 ай бұрын
I wish I was smart enough to have come up with this, 😳 I got the info from the forums I am a part of there are many people who have lost their SLs. You are correct about the fuses being smaller, some people are trying this out to see.
@GNXClone4 ай бұрын
How did you decide on using 30A fuses? I wonder if a much smaller rating would work. I suggest trying out some really "small" fuses, such as 1A. Then if those blow, try 3A, 5A, etc until you find a value that doesn't blow in normal operation. I think that would get you the best protection. My thought is, 29 amps might be enough to start a fire still, but not blow the 30A fuse
@GrooveOn4 ай бұрын
It's a great question, there has been a lot of discussion on the forums and some people have gone smaller to say 20A. No harm in trying, if it blows then you can go higher.

The key objective is to avoid current flow through the BCM in the case of a malfunction, this could be water ingress etc. As I'm sure know I =V/R we know the volts sits around 14VDC however the current and resistance will vary especially as there is a front battery and rear. I have fitted 30A fuses and the simple test would be keep it simple and drop down to say 20A and see if they hold after a few weeks of driving and use.

Did your red battery light come on using the two small gauge with 30amp fuse I’m in process of doing this, is this 12 gauge? All of a sudden, my consumer battery is getting hot. My car is charging the correct way not over 15v I get 13.95 consumer battery 14 starter battery I’m going to disconnect my amplifier and put it to the starter battery and state of the consumer battery.
@GrooveOn4 ай бұрын
No I had no red battery warning lights on the dash. I once had a hot rear convenience battery, but I think ti was due to driving for 6 hours straight twice a week for 2 years that may have damaged it. There was a bad smell that came off the battery too. I changed it with another genuine Mercedes battery, no issues since.

Is moisture the only concern as a source for a short ?

not quite, the BCM over time can be affected by the current surge, especially if the rear battery has been jump started, as it should not be used, only the front.

If your amp is just wired to the positive of the battery and ground, then I do not see any issues. The amp will draw amps to it rather than the other way around.

Is it not risky using a smaller gauge cable despite it being fused?
@GrooveOn7 ай бұрын
I explain at the end of the video that the smaller 10 gauge cable is part of the design mod, the heavy cables will continue to perform, with minimal current now being sent to the BCM. Remember that the current draw is dependent on the demand from the source, to which the BCM does not draw a lot.
