I was truing up some tires for tomorrow's races aaaaaand.... the Hudy starts giving me trouble. Flip the switch... nothing. Flip it a few more times and it then worked. Fortunately, I was about done and was able to finish. I've heard of the switch itself getting gummed up with tire dust and creating issues, so I opened up the switch housing.... no tire dust buildup. I screwed the housing back on.... flip the switch.... nada. Beat on the unit lightly, flipped the switch a bunch of times.... finally ran again. But I'm not confident it will work next time I need it.

 

Suggested course of action? Thanks in advance.

Sounds like the motor is the problem.

Replace the switch, or hot wire around it, and use your power supply switch, to turn it on and off.

 

Manta Ray had the same problem with his Hudy

I fixed Rays a few years ago. Switch was inundated with rubber dust on contacts.

Mine did the same thing so I took my switch completely out and use the power pack to start and stop it. It keeps you from accidentally leaving the power pack on all night.

Good idea. Now just have to figure a way to stop leaving my soldering iron on all night. :dash2:

I put a piece of scotch tape on top of the rocker, creating a shield.

 

It should keep flying particles of rubber from entering the switch through the crack between the rocker and cover.

 

So far, so good -- the switch hasn't quit working again.

I have a lamp over my bench that is plugged into a power strip. I plug the soldering  iron into the same strip. I use the strip switch to turn the lamp on and off. so far so good.

My switch is also going bad. Mine is only two months old. I just leave it in the on position and use the power supply to turn it on and off until I replace the switch.

Me too (just to add weight to how common the switch failure is on this product). I jumpered across the leads and use the power supply to control switching. Problem solved, but you can try removing the switch, blow, dry, compressed air across it and see if it comes back to life.

I operate the Hudy from the power supply switch.

Even though you cant see it there is tire dust in the switch. Try spraying it with Pure and see if that fixes it. After getting the switch working, cut a finger out of an elastic rubber glove and stretch it over the switch housing. That will prevent dust from getting inside it. The switch will still work. I have been doing this for a while with no problems

Mine must be an older model, It doesn't have an off/on switch, just connect the ps leads direct to the truer's motor.

I had the same problem. Cut the switch out and just wired up a higher amperage toggle switch. Now no problems at all.

OK, so I'm back to truing tires today. No problemo for a while, then.... when I flip the switch, the motor starts up a little sluggish and then revs up to "normal". I'm thinking this is strictly a motor issue. Thoughts? Or could this still be a switch issue?

Hook up the leads straight to the motor, and see if it still happens.

I've seen that happen when tire dust gets into the motor and bearings etc.

I'll try that(I know this was suggested before.... finally "listening").

I just replaced a switch for an east coast racer. His motor was exhibiting varying speeds depending on the pressure I applied to the rocker on the switch. Does your switch do the same?

I hadn't noticed; I'll be truing tires again tomorrow... I'll check then. Thanks.

I hooked the power supply directly to the motor of the tire truer; it worked fine, but one relatively short session(30 minutes?) for 3 sets of tires probably isn't conclusive. For one thing, the power is applied differently in the two scenarios. In normal operations, the power supply is already ON and at a set voltage(usually 5v for me); when you flip the rocker switch, all 5v hits all at once. With the power supply connected directly to the Hudy motor, there is no initial power until turning the knob on the power supply.... power is applied somewhat incrementally even if I turn it as close to 5v as quickly as I can. I'll keep using it, bypassing the rocker switch for now. Just for grins, I blew out the switch from "underneath" with some compressed air. I'm wondering if I can get to the switch from "on top" also(?). I've attached a pic of the switch. There are 3 pieces of black plastic:   1. the rocker itself     2. a collar around the rocker    3. the larger housing         Before I break something I can't fix, does anyone know if I can safely pry off the collar(to perform "on top" inspection) and then replace the collar? Thanks in advance.

I can't say for sure but if this rocker switch is like most others the collar is part of the switch. It should be held in by ears that stick out and compress when the switch housing is pushed in or pryed out.

Dennis Samson sent me some pics and a tutorial on removing and cleaning the rocker switch. I'll give it a try and let y'all now what I find.
