Indicators

[Richard TR2]

Hi all, looking for some help / advice. 

I have a TR2 with a three pin Lucas flasher unit. Unit works and the indicator lights all function well. 

What doesn’t work is the orange ‘indicators on’ light on the dashboard. 

If I test the output voltage for the pin (light green wire) from the Lucas unit which runs to the dashboard light,  I get zero volts.

Any thoughts, or should I just buy a new unit?

Thank you all  

Richard

Hi Richard ~

Try fitting a spare unit if you have one.

It does sound like the flasher unit is at fault, why not fit a modern one. I can recommend one if needed.

P.S.

And if you are thinking about upgrading your lights to LED type PM me.

Doesnt that lamp see alternating polarity as the unit flashes ? If so the voltmeter may be confused and it it just a blown dashboard bulb.

Hi Stan,

      not completely sure but I thought the TR2/3/4/4A had a fixed polarity. 

The TR6 and maybe TR5 had a polarity depending on direction of turn.

Correct Roger.

Did it ever work or a new problem?

Have you fitted an LED buzzer unit? If so you need an electronic flasher unit due to led bulb as dash bulb lights occasionally or not at all.

Attach a known working bulb and holder to unit so replacing the dash bulb,, does it now work?

Remove green wire from flasher unit and apply 12 volt supply, does dash light work?

Would suspect the unit but they can be carefully split and the contacts cleaned or check for a dry soldered joint internally.

Many thanks for all the responses, I’m trying a replacement unit at the moment. Will let you know how it goes.

Just to let everyone know it was the unit. Ordered a replacement and all works fine. Thank you for your help all.
