Resistor coil is broke! Can I repair, etc.?

yo-dt · 12-13-2010, 03:04 PM

I have a Hyundai 36 volt, Model HGB-1, Serial Number B1000960. I do not know the year. I had it running and the resistor coil heated up and broke in two. I am having a very difficult time finding a replacement. It looks like it has 17 coils and wires from the Speed Controller attaching at points along the coil.

My questions are:
are there replacements? ( I searched all the "normal" cart sites and
found nothing.)
can I weld the broken pieces together?
I see Yamaha G1 to G9 uses a 21 coil unit that looks somewhat similar
to mine. Will it work?

I believe the resistor's function is to control voltage to the motor. But why would it heat up so much to cause it to break?

Lastly, I don't want to convert this cart to an electronic resistor that pulses the voltage to the motor. Reason being they are quite expensive.

Thanx, in advance, for any thoughts.

Some utility coils are available if you know the gauge of the wire and the length in the coil.

I can determine the length and gauge. Where do I order it from?
Thanx

I have seen large resistance heating coils repaired
with crimp collars and ((I believe silver solder)).

I think the melting point of silver is too low... By the time you melt them you have pretty much destroyed the metal so even if you weld them up I dunno if it would work or if so for how long, you know? ... they only list for like $20... when you find them.

OK Scottb, here is the challenge. Tell me what the resistor is made of and at least one retailer you know that sells these coils. I can find no help with BGW vendors.

Steel. Nivel ... Come on you gotta have a tougher question than that

i belive they are actually nickel cromium or some mix of other stuff

I don't know what that is but this stuff rusts like steel?
