Ok so had a clean up session today on the horn. Managed to disconnect the difficult horn and put 12v across it and that one works too. So we know both horns work with 12v applied. I cleaned up the two pin connecter to the horns as it was corroded. I have good resistance between L2 and the earth horn connector. I also have 12v on the black yellow cable at the horn connector. The only thing I don't have is a good relay at the moment until they arrive next week. I'd say small progress....
So as we have no relay 53 atm to play with we had a quick look at the rear window wiper motor. I think relay 19 has packed in as it was clicking when the stick was pushed forward and it's not now. I checked the soldered joints of the motor and they are all good. We get ignition live 12v, earth is good and around 6v on the green/black wire. We have power to the motor, just no motor. So I'm going to order another relay and look maybe at getting a new motor.
Ah rubbish! Thought I checked that in the Haynes manual before I ordered a new one. Oh well the boy has a spare 19 now. Thanks for the correction rubjonny. It's 72 ugh. Right will order one of those.
