Richard TR2 Posted December 15, 2018 Report Share Posted December 15, 2018 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 Quote Link to post Share on other sites
Fireman049 Posted December 15, 2018 Report Share Posted December 15, 2018 Hi Richard ~ Try fitting a spare unit if you have one. Tom. Quote Link to post Share on other sites
Lebro Posted December 16, 2018 Report Share Posted December 16, 2018 (edited) It does sound like the flasher unit is at fault, why not fit a modern one. I can recommend one if needed. Bob. P.S. And if you are thinking about upgrading your lights to LED type PM me. Edited December 16, 2018 by Lebro Quote Link to post Share on other sites
foster461 Posted December 16, 2018 Report Share Posted December 16, 2018 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. Quote Link to post Share on other sites
RogerH Posted December 16, 2018 Report Share Posted December 16, 2018 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. Roger Quote Link to post Share on other sites

Rodbr Posted December 17, 2018 Report Share Posted December 17, 2018 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. Rod Quote Link to post Share on other sites
