Exclamation Failed Electrics - Horn, Passing Lights, Clock, etc.

G'Day All,

I'm facing Failed Electrics - Horn, Passing Lights, Clock, etc.

No blown fuses located.

However, when 12 VDC is jumpered from another source on the Rover to the clock everything works again.

Wierd?

Thank you in advance for your assistance!

Does the truck have an alarm?

No alarm aside from the anti-theft feature from factory.

Thanks.

Those systems are all on different fuses and grounds, which makes me wonder if your fuse block has corroded out or something along those lines.

If I were home I would offer to help troubleshoot in person!

Exactly what stuff doesn't work? If it things that are on a switched power feed then it could be in the key switch also. The things you mentioned could be in an alarm circuit too. (Horn, lights etc) when you power the cigarette lighter you are back feeding the circuit. Be careful you do not fry the wiring harness.

Could at least some of your problems be your turn signal stalk and/or a loose connection there at the steering wheel?

Good thought Josh - I recently lost turn signals, tails and break lights and gauges - Turned out to be a bad connection on the turn signal stock- Drove me crazy trying to understand this!!!!

Start with the basics. If you have a voltmeter, measure the voltage of your battery, then remove one of the fuses of something malfunctioning (like your cigarette lighter) and measure the voltage of the fuse terminal. They should be the same. That will at least show you have voltage available.

Then measure the voltage at the lighter itself. If you have ~12 volts, then you most likely have a dreaded ground issue. If you don't have at least 11 volts in all of those checks, then you need to figure out why power isn't getting to the devices to begin with.

I have this exact problem it's been kicking my ass for awhile now, so you just checked were your turn signal switch connections?

Yes, pull the stalk and check all.
