1986 Toyota MR2 - get kicked into the weeds.

I would agree with jimi as regards the high resistance. Your thought on the crusty commutator was my first thought, but looking at what you posted my second thought was there is a capacitor on the motor which will produce similar results.
Should be easy to check as to which is correct.

I spent many years working with large DC motors (1000hp+ 3.5 tons) after changing brushes, we used bedding stones to clean/bed in the new brushes. The stones are made(usually) from pumice stone dust which is (gently) abrasive. You apply the stone to the comm in front of the brush and the rotation carries it under the brush, cleaning the comm and shaping the brush.
If you could somehow get it into the motor it would certainly clean the comm, but I can't think how you would achieve it.
I agree with your diagnosis of the resistance readings, even 10 ohms is high. Contact cleaner might work if you could run the motor at the same time. Also agree with your assessment of WD40, has its uses for some things but is very poor for others not much use for your situation IMO.

As I said before your problem is one I had many times as I was a double digit car/project owner. I lost a OE fuel pump which was £500 at the time. Because of this I came up with a number of fixes for the problem.

Sell, scrap or give away cars. This works very well, less cars less problems.
Drive the car, I drove a 30+year old car for two years without an issue.
Remove the pump (if car is off road indefinitely) I checked a pump I took out 3 years ago which I used the process of cleaning and then filling with a "WD40 type oil". Checked it because of this thread and no problems with it.

There is a solution that I would use if I was in your position and facing the cost of an expensive replacement. I have not tried it out yet so it is untested but you could try if you are at the point of getting rid of it. I may have a pump to try it on as I have one car that has not moved for 4 years.

Not wishing to sound pedantic, he lied, the trilogy is in five parts with the final volume being 'Mostly Harmless'

I love the books and even forced them upon my youngest daughter as bedtime stories after having had to read the Harry Potter series to her.

I didn't mind the TV series, if I'm honest.

To be even more pedantic the description changed as the novels were released so your both correct

Oh interesting, I quite liked the film. I mean it was a shock to see that Ford Prefect had changed colour since the early 80s and that Marvin was a totally different shape. But once I'd got past that I thought it was ok.



Not wishing to risk coming over as a bigger pedant than jimi and teaboy but it doesn't end at book five. May I present to you "And Another Thing... Part Six of Three".
Apparently there were comments that 'Mostly Harmless' was a bit dour and Douglas wanted to wrap up the series with a final book. Inconveniently Douglas died before writing it, a state of affairs well known to cause writers block. So the book was actually written by a chap called Eoin Colfer whom I'd never heard of.

So there's the question, should 'And Another Thing...' be considered part of the Hitchhikers Guide? Is it any good? Is it a worthy final chapter? You'll have to make up your own mind.
I have the book, I've read it, it lives on the shelf next to the other five parts of the trilogy.
One things for sure, not everybody was happy. Arthur Dent was apparently angry at the news that he had been brought back from the dead. It says so in Wikipedia so it must be true.

I ignored it for a long time before I eventually bought it.

I just couldn’t get on with it and it remains, somewhere on a bookshelf, semi read.

I have gone back to ignoring it again.

I’m not a fan of the film either.

When I was growing up it was well into the sixties before we got a TV, before that the radio was always on. Sundays was a favourite day, The Navy Lark, Round the Horn, The Goon Show, The Clitheroe Kid, to name a but a few, also remember I'm Sorry I'll Read That Again (look up the cast list), Dick Barton, Hergé's Adventures of TinTin and many more shows that I listened to every week. Later on I graduated to listening to Radio Luxembourg while I was doing my homework and even later listened to HHGG on the radio

We start todays post with ‘Fuel Pump News’ your One-Stop-Shop for news about the, er, fuel pump…

It sat in the tank for a couple of weeks doing nothing and yesterday I hooked the battery to it to see if it still works.
It still works! So that’s good news. I ran it for a couple of hours to, hopefully, clean it up a bit more.


Part of the new plan was that, while the tank is off the car, I can sort out a few rust spots on the floor pan.

Nothing serious, we’ll knock this off lickety split.





It’s just a few spots where the sealer has chipped and water has got underneath.
The first stage is to attack it with a knotty cup brush in the angle grinder. That cuts back the loose rust and takes the sealer off. The only slight problem is that it turns the sealer into something like candy floss. Not as tasty though. It’s a bit gritty.
Once I’d found the edges of the rusty bit I cleaned it up with the Powerfile fitted with a very tired belt.





Then a couple of coats of Hydrate 80 to take care of any remaining rust.





At some point in the near future I’ll get a coat of paint and some more sealer on it.
Easy eh? Let’s move onto the next one…





Hang on, that’s a hole!
A hole in my floor pan!?
Nah, don’t worry, it’s only a hole on this side. It won’t go right through. It’ll be pristine if we look at the inside.





OH MY GOD! IT’S GONE RIGHT THROUGH! IT’S A HOLE ON THIS SIDE AS WELL!

I’m forced to resort to quoting Victor Meldrew and say “I don’t believe it”. It’s an ’80s Toyota. Who’s ever heard of an ‘80s Toyota rusting?
The real problem is that I’ve totally run out of that fibreglass body filler stuff that you use to bog up holes ‘80s cars. If I can’t use the proper stuff I’m going to have to do a bodge job, cut out the hole and weld a new bit in.
“Cut out the hole”? Is it actually possible to cut out a hole?

Anyway…





Rusty bit removed, new bit nearly ready for the very hot glue gun.
And I agree, I could have cut a bigger piece out and sorted out the back side of that bracket that caused all the trouble in the first place. But the reality is that I didn’t. What really needs to happen is that I need to take the bracket off bottom of the car and sort it out properly. But that’s definitely not happening now ‘cos if I fall down that rabbit hole I’ll be too old to drive the damn thing before it’s done.

Oh and there’s another three holes to do so plenty more practice.
