    Ante You got me very interested in your suggestion. The small piece of metal, is this attached to the shaft with the inductor a few inches away? Could you give more info as far as the specs of the inductive sensor. Perhaps if you have something on this type of configuration I would be happy to...

    Hi Ante I was actualy playing around with audioguru and the 5th wheel. As you might have noticed from his posting that in my opinion I think he was sarcastic. So I humored him.

    Hi Audioguru The black lines does represents the connections as you sugest. The switch also selects each pot individually. What happens is that instead of each (SELECTED) pot adjusting between 0 and 100K, each selected pot adjust only between 55K and 85K. It doesn't go to zero and it doesn't...

    Hi Audioguru In the right up the author sugested the following. Depending on the engine's cylinders number, R11 can be unable to set the device properly. In some cases you must use R11=200K and R12=100K or less. I did follow his advice but with with little change. So I thought I could make...

    Hi Audioguru A small problem. I need to change some resistor values in the warning part of the circuit.(Old circuit) When I set R11 to 47K it moans on 1000 rpm. When I adjust R11 to 0 the highest revs I get is 1500 rpm. I need to gain at least another 2000 rpm. Because I cant go further than...
