Tracer atom problem
« on: October 02, 2016, 11:36:11 PM »
I have had a tracer atom for years, every so often I've discharged then recharged the battery and to my surprise it's still good, recently I have been given a 12v nimh battery pack which is 4300mah (the original is 1300mah) took it out to the graveyard where I walk the dog and was dismayed at how dim it is, back home I checked every thing I can, the battery is 12v the bulb is 6v, I know that you can run this from a 2 cell li ion 7.2v battery but if you get the polarity wrong the switch and dimmer don't work and battery voltage goes straight to the bulb (thankfully I learnt this with 7.2v battery so the bulb didn't blow)
I put a voltmeter across the bulb,........2v with the dimmer set to max with the fully charged 12v battery.
got the switch and dimmer to bits and noticed that there was a tiny rotary switch so with the volt meter across the bulb, i twiddled tiny rotary switch, at the point just before it cuts off (starts the cycle again) it went up to 3v but no more, it has brought the brightness a bit but was hoping for more, any ideas?

Will post a pic of the tiny rotary switch later

Hummmm! Now I've got the thing out of the case it will be just as quick to try a new switch.

The rotary switch looks well used. How did you get on with the new switch ?

The rotary switch is very soft metal, it was chewed up by me :-[ I haven't got a screw driver small enough,
I haven't had the chance to try a new switch yet
