Hi there all, I have nearly finished my project of giving my old DT175mx a new lease of life. I have started from scratch with new built wheels, tyres, brand new nos front and rear pipe, re-built engine with new selas and all new bearings, new spray job inc powder coating frame. Nos cables, indicaters, handlebars, plastics. Just put a brand new battery on it and tried indicators.................you flick the switch and they take around 5 seconds to come on. Then they seem to flick ok, although the rear light seems to dim each time they flick on. even when you rev the engine. Will try a new flasher unit to see if that sorts the problem. Tried a different regulater but no change. What does the rectifier do? All help will be appreciated!!!! Jas UK
