[Healeys] Flasher relay advice please

Hang on there Simon... we are talking about a flasher unit... your little round can with 3 terminals...... and the relay... with 8 terminals. 

So, in your case the flasher unit is working fine however, there seems to be a problem with the relay because when LHS is called for the contacts for both the front and rear bulbs close but, for the other side probably only one pair of contacts are closing. 

This can be determined by observing which, i.e. front or rear, bulb is lighting.

The "relay" probably needs adjustment.

This is a littie like brain surgery... takes a little practice.

Best of luck.

BJ8 with combined side/indicators/brake lights. NOT the late phase II with the extra lights.

So,…the relay. By this I mean the round silver can with 1 wire from P to the dash, 1 from B to the 35 amp feed & 1 from L to T8 on the dreaded 8-way flasher relay box.

Now, the LHS indicators work and the RHS don’t. Well, they’ve worked occasionally. My question is this:-

If one side works, then the relay works?? There’s no way that the relay can function on one side only? It sends current down one wire only, so, if the LHS works, then the relay is doing its job????? Right?????


I remain very prepared to be confounded. My logic(?) usually fails when I’m in front of a wiring diagram. In fact, I would be thrilled just to be able to fix the problem with a cheap part.
