I'm sorting/testing various brushed controllers & questionable throttles. Either a faulty controller or throttle can damage each other, but I do not know the technical reasons why. That fact is not a question as I will not repair controllers, but will repair throttles with replacment Honeywell halls. There is no store to run to for replacements, mail order parts are in transit, international border timing unknown's too.
The jc-116 group of 5 controllers needs a resistor of 2200 ohms for a pot to work properly, according to the importer in Tenn. This isn't available, so I'm asking for help on a substitute.
Can I damage the controllers by using the pot without the 2200 ohm resistor connected? I had this pot taped to my bike for a spare for when ebike haters tamper with throttles, pull out the wires & stick back into the housing hole, This happens with brake cut out too. So this pot runs the bike very slow, but gets me home.
Does the resister go in series with the 5v power (R & B), or the signal wire (green)? Maybe its parallel?
I have scrap electronics, Wellar adjustable solder tools & my meter detects to 0.001 ohms. I can work with wire soldered resistors, not tiny flush mount ones. Issue here is eyes & hand coordination. Might be smarter to buy Magura in the future.
The only pot I can use is out of a broken throttle, 5v input gives a normal gradual increase from 0.0 v to 5.1v.
Can I series resistors to get 2200 ohms? If I meter say 3 resistors that add up to 2200, will that duplicate results of the desired 2200 resistor?
Any other part in scrap boards that will work?
