Greetings from a first time poster who's glad you're all here!
I have a BT3000 mfg. ca. July 1994 per the S/N. It has a 15 amp motor.
I've only been using my saw sporadically over the last seven hears or so since I've moved. I've been having a lot of problems with the saw bogging down and kicking breakers or the temp overload circuit on the motor. Fortunately no blue flame or pyrotechnics yet.
Thinking the motor was on its last legs, I removed it and took it to a motor shop for an eyeballing. They didn't get into it because they said parts weren't available but they couldn't see anything indicative of motor trauma. No smoke deposits or odors! I removed and inspected the brushes. They were about 1/2 to 5/8" long and curved to fit the commutator, with shiny contact surfaces showing a some slight crazing (webwork of micro-cracks).
http://www.bt3central.com/images/smilies/frown.gif True confessions time: Due to the saw's location I've had it plugged into a portable plug strip which is plugged into a 15 amp outlet. The temp overload on the strip kicks out frequently and I have also kicked the circuit breaker at other times.
I have three Questions:
I appreciate any and all help!
My best,
Bill Curry

I have three Questions:
- Could the plug strip be limiting the effective amperage reaching the motor causing the lugging down on the saw? I know with 20-20 hindsight that I should have checked this out using another outlet but, hey, it's all torn down and if this is a motor issue, I'd like to find out now.
- The original belts look great with no cracks evident on bending--any reason to replace them?
- With the saw torn down, it's a good opportunity for upgrades...heard the shims on the 3100 were a better design. Do you recommend upgrading the shims?
I appreciate any and all help!
