Giving myself a headache trying to understand CAN, and why its not quite working. The cheap logic analyser I got works well, not bad for 8 quid!

Odd, Can high should be the inverse of Can low it is a balanced signal, looks like the wave forms are in the wrong place.
BTW have no experience of automotive can but it is based on 485 control originally developed by Phillips, in the past we did 485 integrating AV systems into HVAC / lighting control, don't see it much these days.

Covert install in the Vito.

Ran out of time this weekend, but all there is left to do is connect the inlet and exhaust for combustion, connect to the battery and prime the diesel line.



Should be out of harms way under the seat.

You might need to go easy with the TIG one lest any rough treatment damage the cup. You could maybe have the same concept but with a bent open-ended spanner supporting the rubber shaft just below the torch head. This would work no matter what size or style of cup you have on.

Yes, a good point and one I'm mindful of! Do have another one for the TIG torch that I made a year or so ago but your suggestion sounds better. Cheers!

Can you get brass core plugs to stop the decay?

I think you can get them actually, but using properly mixed coolant will stop any rusting. this motor was older than the hills when I got it, and I’ve yet to even run it myself.

 

[Morrisman]

Might be worth getting the power washer in through the holes and give it a good blast out while the plugs are out, even a garden hose would do.
It's an awesome looking car

I did use the garden hose on the jet setting, and I also removed the water pump and thermostat housing, to save getting rusty rocks and gunge in my brand new pump and ally radiator.

Reminds me of when the Escort froze up one winter, which core plug did it pop you ask? The one behind the flywheel that was fun changing in the car park of the flats we lived in at the time.
Funny how the gearbox was much heavier going back in than it was coming out, and before you ask I was younger and topped up with water not pre mixed coolant back then, not something I do now, lesson learned.

There are 12 plugs on this motor, but I can only reach four, without a major tear down, so those will be changed and a prayer said for the others....

Depends on if it's single wire, or twin wire CAN.
But I have seen twin wire where high and low don't mirror each other, and low is simply a lower voltage.

Knocked out 2 money boxes for the grandkids, saves putting them in the bin !

It may just be my setup. The logic analyser only has a ground reference so it may think that the 2.5v and 3.3v? Of the high line are the same? Did I mention this is giving my a headache? My day job is C# and sql, this low level stuff hurts
The transciever chip has a Vref pin which is supposed to be Vcc/2 =1.8v, but its measuring 0v.

Im using a 3.3v can transciever TI VP230 as my esp32 is 3.3v, and that is the recommended chip, there is a hint that may be a problem. I will order a pack of level converters and a proper 5v CAN chip.

I need to get an ossiloscope!

I just had a play with the induction heater just using a lipo pack.

The current and power will be much higher running on 50v.

Is the analyser a hardware box, or just a s/w package? If the latter, what is needed to run it? Do you have a link?
I need to get into CAN so that I can work on EVs.

Software Ive been trying Sigrok Pulseview, https://sigrok.org/wiki/PulseView free, and Saleae Logic, which is not, but it appears to work and hasnt askd for my card yet. www.saleae.com

Ok, I try not to post on things that I am not sure of which is why I referred to BMS networks perhaps I should have Googled automotive Can However, if it were BMS I would be removing nodes to see which one was bringing + or _ down, when both lines returned that would be the faulty node found, with all nodes out and still bus shorted to ground that would be cabling.
I did not know that single wire can existed and by definition it would not be can as can needs both lines twisted together for spurious signal rejection same as Cat 5 / 6 etc. network or a balanced audio cable.
I now want to read up on can, not because I need to just because...

A two channel PC scope will not cost a lot, for occasional on site use we had a Tenma USB scope which I think is just a generic Chinese scope sold by CPC / Farnell the same item could have come from any of the usual suspects with a different colour case and different name on it, just we had an account with them.

Pretty intense day working on a pneumatic actuated alluminium profile chop saw.
Troubleshooting it the entire morning and solving the problems after lunch
6 hours working on it
All the pneumatic lines were leaking from the push connectors.
Found a stucked solenoid valve .
And some other air leaks.
It's working now but I'll have to replace all the connectors and tubes

Nearly finished making some camelbacks
Seriously thought about starting to machine a diff for a lister nobbly.
That’s a horizontal borer or devlieg job
Going to need to make some Microbore insert bars for max accuracy and finish

Good stuff mate


Ps that looks like a multico morticer in the background

Id know that table setup from a mile of, lovely machines

Has your got the square hoover motor
