12v power for a tyre compressor
2 questions about the 12v power sockets...
In my 159 sportwagon, there is a 12v power socket in the front with a 10amp fuse. I have a tyre compressor (replacing the spare tyre) that draws between 10 and 15 amps, so blows the fuse when I use it in the front socket. Using the rear socket is not an option as it doesn't work and the cable isn't long enough to reach the front tyres anyway.
What are the implications of using a 15amp fuse instead of a 10amp fuse for the front 12v socket? The wiring must be pretty feeble if it really limited to 120 watts, or do 'we' think it could handle 180 watts?
Last summer I destroyed my rear power socket somehow. It was fine before I used my trusty multimeter to check which way round the +ve and -ve (for another job), but afterwards there is no power at all at the socket. Something must have shorted, yet the fuse is OK. Its all a bit odd really! The rear wiper shares the same 15a fuse and it was fine until a few weeks ago, but now the motor has gone on that too.
Any suggestions for restoring power to my rear 12v socket anyone?
What route through the car does the wiring take to that socket?
Are there any other inline fuses to the rear socket other than the 15a under the steering wheel?
Does anyone think the now failed rear wiper is related to the same problem?
