Busted jigsaw motor - fixable?

My replacement drill battery was going to be =A325. I got the wrong bat= tery for =A310 (for a different drill) and moved the cells over.

Red meat isn't bad for you. Fuzzy blue-green meat is bad for you.

My Honda CRV needed two ABS sensors. =A3160 each from the dealer here (= without fitting, easy enough to do myself), not available elsewhere. I = got a friend in another newsgroup to buy two in America and ship them ov= er to the UK, which I think ended up at =A3110 each.

Then the same two sensors needed replacing on my VW Golf. =A312 each fo= r genuine parts of =A35 each for copies. I will never buy Honda again.

I haven't read all the replies but he stated he had a shorted coil. Wouldn't he have to undercut the commutator or at least scrape out the safarcous to tell?

I am not familiar with Mexican quality. Is it as s*it as Chinese?

And depending on the supplier it sport about a 75% failure rate. Could have asked the price prior to authorizing the repair.

I would check the tension on the belts. Sounds like it's too high; which will cause this problem. Wasn't a Leece Neville was it?

utator and perhaps sand the end of the brushes a bit, not a lot, just ge= t the glaze off of them. I've extended the life of a lot of universal mo= tors in such a manner. ^_^

I looked up a wiring diagram and that kind of motor apparently has each = coil connected between neighbouring contacts on the commutator. Not the= way I expected, I always thought they'd be at 180 degrees to each other= , but apparently the brushes always connect several coils in series. So= I tested every neighbouring pair with an ohmeter, and one pair was 10 t= imes less resistance, so I disconnected it.

Now I've just had a thought - I've done something daft haven't I? If on= e coil is disconnected, then the series of them is also disconnected, wh= ich explains the rough running of it still - it's only conducting in the= other half? When I take it apart to think about changing the brushes, = I'll do more resistance tests between the brushes at various points in t= he rotation.

However, if all I had was 1 shorted coil, and there's always 12 in serie= s, why would that bother the motor in the first place?

Does the name Tanaka sound familiar? Denso, Bosch?

There was a discussion a couple of months ago here about IIRC a starter whether to buy a low price gamble or exact replacement.

A "growler"?

We've had a hot, dry summer this year. It was so hot that one of my neig= hbors said his wife even thawed out.

Okay, I'll take your word on this. (And he confirms it.) I didn't know this could happen more than one in a million.

My wife's Lincoln was 45% foreign sourced. It should be on the sticker.

That is more than some "foreign" cars built in the US. Honda Civic is

65% US/CND, Toyota Avalon 70%, Camry 75%, the same as Corvette.

Yeah, we remember George Wallace and Forrest Gump.

Too warm to be bothered starting a fight.

People who design power tools are idiots. They never provide enough cooling for the motor. I sent a brush cutter back after 3 weeks because the motor burnt out with 30 minutes use.

I assume you mean in price. Odd how they claim we're giving off too muc= h CO2 for that global warming bullshit, yet it's more expensive to buy i= t=E2=80=BD
