Turn Signal Conundrum

[macdonge]

Finished wiring up a new turn signal switch (VSM 900 from one of the major reputable suppliers) for my '30 Roadster recently - but only after some effort to find a short circuit that would cause the fuse to blow whenever power was supplied to the circuit. It turned out to be a short inside the switch itself (see pics). The blue wire supplies a common load bus with 6V (first picture). I found that the black ground wire was shorted to this bus (second picture). A bit of tape and bicycle tube fixed it (third pic)!

With the exception of a dim pilot light, all was fine thereafter in terms of its operation. Then I decided to change out the cheap thermal BV535 6V flasher that had been supplied with a Novita LL535 electro-mechanical flasher. Well, the flash rate improved a bit & the pilot light brightness improved substantially (and it was nice to hear the relay clicking - something the thermal flasher doesn't do) but when the lights are turned on (in either parking, headlights or bright position) the flasher (signals) doesn't kick in.

Thoughts anyone?
