i have wired up my towbar with a 7way bypass relay and heres whats happening - indicators work fine -side lights work fine - brake lights work fine --- until i switch on the hazard lights which knocks out my side lights and indicators - anybody any ideas ?? - thanks in advance

Check everything is earthed correctly and sufficiently :)

earth problem ?? even though all the other lights are ok ? just when hazards are put on - i will recheck earth but pretty sure its ok

I had the same problem when I rewired my rear lights for facelift ones. Was a bad earth

ok i will try that - thanks

Hi again – I finally sorted it – as I had done it with scotch clips
I decided to solder all the joints and the fault was still there and as I was
holding the relay I must have moved one of the joints at the terminals and lo
and behold the unit kicked into life – so it was all or nothing at this stage and decided to prise open the
relay and the positive and negative terminals
came away from the circuit board – so I decided just to solder a couple of
wires onto the circuit board and reconnected them and all other wires - and BINGO all sprung into life – so it must
have been a dry solder joint in relay from removal from my last car 6 weeks ago
– so end result is all is now working fine - thanks for your advice -- robert
