1992 Hymer B564 External Lights Problem

[Flamenca]

I have a 1992 B564 2.5 turbo diesel on Fiat 290MSJ base and would appreciate some help regarding the electrical wiring and relays associated with side lights/headlights.

Yesterday on a multi-stop trip the sidelights would not always come on using the stalk switch on the steering column although they would always come on using the parking lights switch on the fascia. I have assumed that it is either a loose/corroded wiring connection or a sticky relay. Unfortunately, I do not have a decent wiring diagram for the base vehicle and do not know the location of the relays associated with the lights. There are some relays next to the fuse box in the glove compartment but do not know what each relay does.

Does anyone have a wiring diagram for the Fiat Ducato base and maybe a diagram identifying the relays in the glove box?

I have also started this thread on the Classic Hymer Facebook group so no need to direct me there

Thanks in advance.

I seem to remember that Paul Badknee has had the problem with his lights not coming on on occasions & that he had to dismantle & clean the stalk.
On my 1989 vehicle the side light s& the parking lights must have been on the same circuit as if you turned on the side lights & then pressed the parking light switch the lights actually got brighter.

Here you go

Ducato headlight again!

I’ve posted about losing my headlights before but this time in heavy rain I lost the lot, side and head. 2006 no airbag. Cowels off, wheel off, unplug electrics. Full cassette, lights, wipers the lot. Take out the six little screws and split but take photograghs so you know what goes...

Thanks. I have found a wiring diagram for the light switches and, yes, the stalk switch and parking light switch both have 'outputs' to the common sidelight circuit. The only difference is that the stalk switch is connected to the ignition circuit and the parking light switch has a direct battery feed. I am considering having 'automatic on' for the sidelight circuit when the engine is running by simply installing a relay from the ignition circuit.
