QUOTE However worth all those whom experienced issues to contact Steve and see if it is a underlying design issue which can be resolved, or is it a peculiarity with our track which we can't think of why
Here is the e-mail i've sent to Steve:
"Hi Steve,
Earlier this year I bought one of your PWM controllers.
I was using it this weekend when it suddenly developed a problem. It had been fine all day Saturday when testing but during the racing on Sunday it suddenly started cutting out. It would then almost immediately start again. This problem was intermittent and unpredictable in that it might work well for a couple of minutes or it might cut out several times in a lap. This happened once before at a different club where I was told the power supply was not regulated so I stopped using it immediately for fear of causing damage. The power supply yesterday is regulated with more than enough amps for the type of cars we were running, 1:32 Retro.
Strangely, others using Truspeed controllers also had problems but I'm not sure what their symptoms were. One of my clubmates also used one but he had no problems. Our club has recently had to relocate to a new premises but the track wiring is basically the same and we had never had any problems with controllers cutting out before.
I would be grateful for your advice. If you need to know anything about the club power supply or track wiring feel free to contact Mick Kerr: (Micks e-mail deleted here)
Kind regards
John Roche
PS I've just had a thought, could the problem be the "plug in cable"? If so, how often should it be replaced as i've not had much opportunity to race due to all the work involved in the club relocating? "
