TR Rob Posted April 22 Report Share Posted April 22 (edited) On my “Drive It” run yesterday,the green indicator warning light stopped working. However, if I gave the light a bit of a tap, it came back on flickered a bit and then went off again. I thought this was a classic bad contact on the bulb holder as everything else worked perfectly. This lunch time I took the lamp holder out, removed the LED bulb and tested the contacts with a test lamp, the intermittent fault seemed to be the centre contact. So with battery isolated I cleaned the centre contact by lightly sanding the contact to shiny metal. On retesting, my test light now stays on constantly with slightly less brilliance and a slight pulse. The electronic flasher unit is ticking and the LED indicators are working , but the warning light is not pulsing with the flasher unit and does not go off when the indicator lever is in the neutral position. Further testing , the indicator light goes out completely when I remove the P wire, I did this as I was wondering was I getting a voltage leak from somewhere . I am now thinking that with this test and the lower brilliance and slight pulse I have damaged the electronic flasher in someway. I’m beginning to wish I had left this alone as this seems to be another TR one step forward two steps back scenario . Any advice as usual accepted with thanks Edited April 22 by TR Rob Addition Quote Link to post Share on other sites
Lebro Posted April 22 Report Share Posted April 22 (edited) I suspect you have damaged the flasher unit, by accidentaly shorting the bulb contacts together. the bulb is driven by a small transistor. I can easily replace this for you, (I blew one myself a while ago by testing the unit with too high a wattage bulb) Bob. PS. If you like, I can send you a replacement unit,( I have a spare one) then you send me yours, I repair it, & keep it for stock Just cost you the postage. I know yours is -ve earth.

Lebro Posted April 24 Report Share Posted April 24 As suspected, blown transistor feeding the pilot lamp. Now repaired, & on it's way home. Be careful not to short the pilot lamp's contacts together, or it will happen again !! Bob Quote Link to post Share on other sites
