This time we test the alternator and learn a bit along the way
Throughout the project we will build tools to help us along the way, the custom tools we build, we will upload our how-to videos

Hi Dave, I think that W connection/wire is used in Diesel applications where there is no coil to take the pulse for an electronic Rev counter, the pulley size would be matched to the rev counter and motor and use the sine wave to calculate revs, for your application remove the wire 👍

Yes, that makes sense, thank you. 😊

Nice one

thats a self regulating alternator with the rectification pack built in , so no need to have an external unit. The W wire is a rev counter feed.

Well done Dave. Good explanations for those who don't know the principles. Comments are correct re. the "W" terminal.

Thanks Bob, comments have been very helpful 👍

Great job and excellent explanation, everything you said was correct, you also avoided the trap of too complex an explanation that would confuse those who do not have a handle on electrical principles. Well done again!

I think a battery sensing wire seems to be used on later ecu cars,to protect it maybe?

I think when you were spinning the alternator up, you were spinning it the wrong way because the fan blades of the alternator, supposed to suck carry and push push air through to keep it cool I’m not 100% sure, but I think I’m correct I may be wrong Please check

@DavesGarageuk 6 месяцев назад

Must be the right way. Most engines run clockwise. Maybe it looks weird due to screen refresh rate?

Great video Dave. Induction doesn't even need the wire to be coiled. A conductor, a magnet and relative motion will induce a current 👍🏼👍🏼

Thanks for the info!

The W terminal also connects to a manifold heater on petrols if fitted

Ah, OK, that's interesting

It’s a phase tap wire for Rev counters on diesels . It puts out about 7.0 volts .. don’t need it so forget about it .

Thank you 😊

Interesting stuff Dave I’ve actually learned a lot from your channel lots of interesting things going on I must admit I’ve never really thought about how they work before now I know 👍

@DavesGarageuk 6 месяцев назад

Cool, thanks 😊

Could be miles off here but I wonder if the 'W' is the wire for the rev counter feed. Sounds strange but alternator speed must relate to engine speed. I remember many years ago fitting an RS type dash to my brothers MK1 and we had to run a wire through the back of a fitting on the rev counter but I don't recall where it came from. It could well have come from the coil or distributor though. It's amazing how much you forget as time moves on and you don't use the knowledge and skills.

Hi Dave very much enjoying all the videos!!!, as stated W wire is indeed waveform wire for the Tacho.... I was told many years ago when I asked at my starter motor and alternator repairers that the old Lucas ACR alternator and the like had blocking diodes within them to deal with overcharging.. the modern type this is dealt with by the ECU but guess maybe some are different....depends what car it came from???? keep up the great content. regards Chris

Thanks Chris 👍

W=Tacho

@micktuck5377 6 месяцев назад

It should have a voltage regulator integrated to your alternator to stop it over charging Dave, you don’t need to connect terminal W mate far has I know. As per other comments

Brilliant thank you 😊
