Dash lights

High guys I have owned my cabby for around 18 month and only really driven it around 8 months. In that time I have had 5 10A fuses blow for the dash lights.  I know this fuse does dash, interior light and number plate.  Does anyone know why so many would blow. Did think about putting a higher rating fuse in but I don't as its blowing for a reason and could be unsafe to do so

Yes, a burned gray/blue wire shorting to ground usually.
Or the interior lamp switch is shoring to ground instead of through the bulb.

I will tell you that in the 50 years of playing with electrics, Never OVER FUSE….  

Lucas designed whole electrical systems to protect the fuses…and usually the wires would release all their stored up smoke before a Lucas system would blow a fuse.

I can remember one time in desperation over loading a circuit.  To find the wire, as I couldnt see it… This was back in the old days of computers when Back-Planes were wired from pin to pin to post… Thousands of miles of wire in a Main Frame.

Needless to say I found where the wire was shorting.  I only had to remove 100 feet of wire from pins, then re-wire it with a "wire-tool"  Saved the company a ton of monies, but it was a 10 hour job to re-wire.

In the really oldie days of my youth, most aircraft fuses were in ceramic cases to prevent fires, so you couldn't see the blown ones.

Look at your Headlight switch for the gray/blue wire unplug the connector and measure the gray/blue for resistance to ground… if it is shorted, then follow the wire to where it is burned or touching a brown wire or frame member.



 

Cheers mate I will do that hopefully it should be easy to find. My interior light is broken in the way that's it dose not clip in nearlly hanging out. I'm glad I was right about over fusing

Just make sure the interior light isn't shorting on the metal work.
water in the number plate lights.
Ans Yes as Briano says never over fuse….

the most common cause is bodged radio wiring. there isa dash light feed to the radio plug which is often cut and left dangling by the wire bodger

My radio is bodged (not by me) cut and spliced wires everywhere will look at that as well cheers
