This is the greatest how-to place for sure!
Thanks for the post!
Prior to starting the saw, I did look everything over to check for loose connections, frayed wire and scuffed up insulation. There is one place in the power cord outer sheathing scraped off, but it did not cut any of the insulation off the 3 wires inside.
I did wiggle that relay toggle and it did not bind at all.
The recent solder joint is where I put the tagged wire back on where it was before the guy took it all apart to have the motor tested.
The guy I got it from said he had the motor tested and that it was not bad.
He was having trouble finding a capacitor for it, and in the meantime, found a running(on 220V already) Dewalt radial for his shop and installed that.
I had the cover off, exposing the relay board as shown in the picture. When I threw the switch, I did hear and see the relay close. I did not look to see if it opened back up however. Then, when the capacitor blew, my focus was on getting it unplugged! Luckily, I was NOT in line with the end of the cap or I would have gotten blasted for sure.
You seem to have the real knowlrdge I lack in this situation.
A novice such as myself may do more damage poking around and trying this and that...so,
what can you offer for troubleshooting steps that will not hurt the motor further?
There is no blade mounted on the shaft yet either, but I didn't think that would matter at all as far as whether the motor runs properly or not.
Can I remove the blown capacitor, jump the two leads and test for the relay to close and open?
I guess I need to know exactly how this thing should act when turned on also.
From what you posted, am I correct in the following?:
TURN ON THE POWER-relay closes, energizes capacitor and starts motor?
THEN-somehow the relay times out and opens, disconnecting the capacitor from the power source, and the motor runs on current that does not go thru the cap?
I have an old drill press with a 1/4HP 1725?rpm motor on it with a cap housing on it...I can tell by how it starts up it has a centrifugal start/run winding switch?
It starts with two distinct sounds and a 'click' when the run windings kick in.
Do you think the radial saw motor has this type of setup as well?
When it powered up, it did seem to be running at high rpm (3450), like I'm used to with my 10" table saw.
Looking forward to your reply
...I really want to make some sawdust with this thing someday
