I am normally not too bad with electrics, but I think I need some superior advice.
On the hatchback, the handbrake switch earths directly to the handbrake warning lamp.
However, on the cabrio, the electric hood uses the handbrake switch as a safety device and earths to one of the relays in the boot.
I have got the Fiat manual but I cannot find how the relay links to the handbrake warning lamp.
To make things worse , the factory alarm has been replaced by a Clifford system, which I haven't got a clue how it is wired or operates!
Now here's my issue. The roof worked a couple of years, when I last used it. But now, nothing, nada, niente. The handbrake warning lamp does not illuminate when I put the handbrake on, but it lights if I press the fluid switch on the brake cylinder.
I have tested the handbrake switch with a multi-meter, and it appears to work properly, creating a circuit when released.
Would I be right in thinking that maybe the relays have degraded over time, or should I be looking for something more basic?
The only fuse I can find is the 40A one under the bonnet, and that is fine.
There is, what appears to be an earth wire, spare under the bonnet, which I may have dislodged when I have been charging the battery, but I have tried earthing it and it makes no difference. It is on a small loom near the battery, but the other wires are cut, so it may be part of the factory alarm system. HELP?..................:bang:
