B and B Shark troller

Can someone tell me what the knobs on this controller do?

Thanks Mike. I'm trying to repair this one.

While there are many different versions with many more features, I need to ask - is below a decent description of the more typical dragtroller:

Pulling the trigger throws a relay which starts a timer but also launches the car through the transistor which is limited by the speed control knob. When the timer runs out, it throws the blast relay and the motor goes to full power?

I've fixed of bunch of Greg's controllers, the most common problems are broken wires and bad transistors. What doesn't work on your controller. I was recommended by Greg Bridgewater to repair his controllers when B&B went out of business. I can repair any of his controllers, I stock all the parts. You can see our controllers on facebook:

Thanks Brainchild

here is a video of this controller sort of working. The unmarked transistor is a non drag difalco that I put in to see if it would help. As I see it the timer circuit works but that is all. Please take a look and let me know what you think. The right transistor would help but I am not sure exactly what the other features are supposed to do.


PM me or respond here. We are happy to pay you whatever you say is fair.
