Convertible top reset after battery replacement

[gookah]

The brake switch does indeed have two circuits, but one is used for the DME as a switch integrity test circuit.
It's a belt and braces test that sends a second simultaneous signal to determine that the pedal is, or is not, actually pressed.

The other switch contacts link all other circuits together, including roof and brake lights, so if brakes lights are on then roof should have +12v as that side of the switch is working.

Interesting as my brake lights worked but the roof did not until I replaced the switch.

Never had a problem with my roof when I replaced the battery.

May be different arrangement on the M?
Diagram is for the M52 and M43 engines?

So you suggest I change that switch anyways. Seems like an easy job

Sorry but I can't open it but it might just be my software ?

Edit: All good now.
