Mr. Brent could not or did not want to sell me any sensors, I practically found the door closed and with much disappointment I had to manage completely alone (after all, not everyone is like Nelson Pass) looking for compatible sensors by buying engines on engines of other brands, spending a lot of time and money on engines to find compatible sensors and doing extensive testing; of the TT 101 only one sensor was defective but in the end I replaced all 3 sensors for consistency and uniformity of performance.
Now that I have the discovery and the knowledge, I'm sorry but I will do exactly as it happened to me, whoever needs it will have to spend time and money in research or stick to the tram and be satisfied.
