Re: gtv rear screen again
Could you guys see if your timer has broken? This may be the common factor...
I replaced the fusebox on mine, and ran a voltage check on mine. I get around 14V at the battery, 13V in the footwell, but only 11 across the bottom of the screen.
Speaking to Jamie Porter about the drop, he said that often the 10-minute timer cutoff breaks, causing the various parts of the circuit to over hear, and cause damage to the fusebox. This ties in with the damage I saw, which seemed to be from poor contacts on the fuse, rather than a brief over-current.
I checked the timer with a light bulb across the relay pins (85 and 86 from memory) and lo and behold, the timer doesn't work. Jamie's suggestion was to take the high current out the fusebox, fitting a relay in the back to be switched by the existing circuit.
Of course, this does not explain the voltage drop in itself, but to remove the rear trim to check the connections is halfway to rewiring the whole thing anyway, so I think I'll take Jamie up on the job.
If anyone with the same problem does the same check, I'd be interested to hear what they find...
