Hi all got some second hand PIAA lights sent through to me today, the lights are in excellent condition and in full working order (wired straight to the battery for test)

However they will not work off the existing wires of the car, I put the full beam on and front "fog" switch on but nothing, tried the plugs that the lights attach to on a multimeter and there is nothing / no change when the lights are turned on

The light on the switch does come on

I’ve read on Rb5 owners club that it can be an earth or relay problem? If so where are the earth points for this loom?

Also am I right in thinking there should be a white PIAA relay between the battery and n/s/f headlamp? If so I don't have one but there is a connector there sticking up exactly like the connectors the lights connect to, just with an added wired and what looks like a bullet connector

Any help would be much appreciated

 

you need the piaa relay to switch and also power the lamps safely i have the proper piaa wiring diagram and pretty much a whole set up spare ( appart from wires) if u need any thing

 

could you pm me the wiring diagrams? can rule out some things if i know i've got everything i should!!!

 

ye ill sort it tomoz when i go to the garage and get it

 

cheers that would be a big help

 

You have an RB5 and it came with no driving lights? At all?

 

it came with lights but the reflectors where corroded, they haven't worked since i've had the car

all the wiring is still there except i think the PIAA relay, when i find out what i'm missing i can order the parts then

 

Ah, fair enough. It ought to be wired correctly, so should be starightforward.

 

anyone have a picture of their PIAA relay in situ?
