Hi, use one of these for electrical work, got 200k on the clock, no real problems except normal wear and tear. New turbo 3 years ago. Anyway, lately been loosing power and the orange glow plug light comes on. Dip clutch, turn ignition off and on, lift clutch and away it goes for either lots of miles or a few hundred feet and same again. Power goes, light on. I'm thinking of electrical fault as ok for little bit when switched off and on. Hate to spend any money on it as high mileage beast. Is it best to put on a diagnostic and hope its just a sensor or is this a common known fault. If its ECU then is it time to say goodbye. Thanks for responding to any who do.
