Hi All

This is my first post so a howdy hello and thanks for the information shared thus far

I'm finding myself with an interesting problem on my SG9 XT

But first, let me share what I've done that makes me think might have sparked the issue (no pun intended, you'll get it later ;D )

Changed brake pads (front and rear)
Oil change
Recharged Battery (she's been standing for a month or so)

So after I refitted the battery I start the engine, let her idea a bit and took her for a test drive.

First thing I noticed was that I needed to apply more throttle but just thought that the ECU needed to re-learn

But then I noticed my instrument cluster was dead ; only fuel gauge and the temp gauge was working. I probably drove 2km and decided to turn around and she stalls on me. :-\ I try to start her again and the battery is DEAD now I'm confused

I call the wife she gives me a jump and I manage to crawl back home

I manage to track it down to a popped fuse #14 Meter Fuse under the dash but also notice fuse #8 ABS fuse has blown. See attachment

So I replace both fuses and off I go. So I decide to use her every for about a week and suddenly once morning INSTRUMENT CLUSTER DEAD :'(

I've replaced roughly about 2397 fuses and EVERY time I turn the key #14 Meter Fuse FUSE POPS

What I know at this point is that this fuse (according to the wiring diagram) also does the following:

Signal to the alternator
Signal to the ABS

Has anyone experienced this issue or might have an idea but to me more direct HHHHHEEEELLLLPPPPPPPPPP!!!!!

What exactly do fuses #8 and #14 protect throughout their respective circuits? Do you have a wiring diagram? The colored circles in the photo represent two different circuits. The 30A ABS fuse leads me to believe this circuit is directly or nearly directly connected to the positive (+) terminal of the battery and / or alternator.

My guess? Look for an intermittent direct short to ground (earth). Double check your repair work. The two problems maybe unrelated.

Remember you have a South African model car, so these circuits may be different from, say, a North American Market car in terms of what electrical systems these fuses protect.

I once had an Audi (Type 85) 80 quattro that sat for a awhile getting a new timing belt. All went well for the first two miles, after the new belt was fitted, and then the car died with a dead battery. Turned out mild corrosion prevented the voltage regulator contacts in the alternator from completing a circuit so the alternator's field would be excited by battery voltage, so the battery was not being recharged. I cleaned the contacts and the problem was solved.

@r3spawner looking at the wiring diagram for the USDM '06-'08:

fuse #14, 10A = FB-22

FB-22 load:
• Combination meter
• High beam relay
• Daytime running light relay
• Clock

fuse #8, 30A = FB-28

FB-28 load:
• ABS control module
• VDC control module
