Hello: I cannot fix this if I don't understand what is going on. Any help will be greatly appreciated. Here is the puzzle: I have a wireless controller for a snowplow. the plow started to act sporadic or not at all. I took out my multi-clamp-on meter to check voltages at the plow. All appeared correct. I clamped the meter onto the plow in order to look at something and then forgetting about the meter I attempted to operate the plow, expecting nothing to have changed. Amazingly the plow worked like new. What!?I was ecstatic (I really need my plow ). I gathered up my tools. Retrieved the clamp-on-meter and thought... "fixed". Tried the plow one more time and...nothing. Went back to the plow to check voltages thinking o.k. it's a loose connection somewhere. Got out the clamp on again. Clamped it near the receiver just to secure it, so I could take some voltage readings. Found nothing wrong so I tried the plow... now it works. OK. long enough story. With the clamp-on-meter set to voltage and placed at or near the receiver the plow operates like new. Turn it off and it stops working. I suspect the meter is amplifying the signal from the hand held controller. The receiver end of the electronics is encased in resin so I cannot get at the components. If I am correct, I'd like to put together an amplifier to replace the clamp-on-meter. Does this make sense? Any sketches known that I can build? ( the wireless hand held is over $200 and I am not ,at this point positive it is the problem. Any suggestion will be appreciated. sorry for the long story.
Sorry: I ment the batteries were changed.
I could just leave the meter on at the plow but I would rather come up with a more permanent fix.
Hello: The plow is a Snow-Way. A medium duty snow plow. The clamp on is a hand held multi-meter with a jaw that can open and be placed around a conductor in order to take amperage readings without having to insert the meter into the conductor. Voltage and resistance reading are taken via the usual probs on the end of leads (+ and - ). If I was confident in sending pictures I would, but I am not. I hope this helps give everyone a clearer picture of the set up is. It is an electrical problem and I think it is with the transmission between the hand held transmitter and the receiver and the clamp on meter is somehow correcting the problem. I could just leave the meter on at the plow but I would rather come up with a more permanent fix. Thank again. Any ideas?
and if there is a electrical circuit I can build to replace the meter permanently.
re-checked everything. All is OK. No bad grounds. No broken wires. Voltages all check out.Just to clarify. The multi meter is not in physical contact with any thing only placed near the receiver and the wiring and then the plow works. The meter only needs to be in the "on" position.I believe the meter is intercepting the signal from the transmitter and amplifying . I'd like to know how and why this happens and if there is a electrical circuit I can build to replace the meter permanently. It is a 12 volt system. Thanks again. Any help is appreciated.
