Today March 8th I started my TAMD60b starboard engine only, for the first time since the winter lay up. She fired immediately and ran as sweetly as a "nut", with minimal smoke. The reason it was almost instantaneous is that (as an experiment) I have converted it to a pre heat (cold start) system.
This entailed the removal of both the inlet manifold and the intercooler, and the installation of both, heater plugs in the manifold, one opposite each cylinder inlet, and a TAMD"61"(or was it "70") pre-heat coil fitted to the intercooler outlet where it joins the inlet manifold.
This is all fed from the starter supply immediately below (convenient) through three starter solenoids mounted on the forward side of the intercooler housing, one for the heater plugs and one for the coil, with the third, supplying earth when switched (for safety). As yet I haven`t sourced a timer relay (but am soon to do so) for now I have to energise it all via a "bit of wire" touched on the the supply (yeah! there is a little arching!). This will rapidly be replaced by an illuminated push button on the dash, which will (through the timer) hold the heaters on for 30 seconds, after which time the engined is started. Another benefit (I see) is that after the engine starts the small amount of "Hunting" that occurs can be negated by the further manual use of the pre heat. I tried it today and within 10 seconds of "depressing the button" for a second time the hunting had stopped.
I obviously haven`t had time to properly evaluate this system as yet and would gratefully recieve all comments, but the additional benifit having fitted this system, is that I am obviously, initially getting better fuel burn thus less smoke on start up (got to be good). It is my intention to finish the Port engine in a few days and "full" trials will start in earnest.
If you have any comments on to this installation I would gratefully recieve them
