Re: Daihatsu diesel generator troubleshooting

It appears to me to be somewhat of a problem here engineering wise to crack this one? As there are more than one ways of skinning a cat ( as they say ) perhaps a different angle of attack might be the way to go. A personal approach maybe. So I put it to you in a different format. Winding back the ol...

Perhaps the same team who designed the system used to work for Boeing, they have it worse that computer taking over and bringing down fully loaded aircraft. Perhaps computer designed systems...

Re: Daihatsu diesel generator troubleshooting

Don't see many ( if any ) 36 v engines but lots of Common rail stuff circuits on 5-5volts for modules and -5 volts for oxy. sensors etc. However you are ( intentionally or otherwise ) on the right track here mentioning voltage. Think about other measurements in the voltage field era and see if you c...

Re: Daihatsu diesel generator troubleshooting

Remember my " What's the difference between a R/H machined liner and a L/H one? "
Nobody got it over several months period.
The answer was staring you in the face every time our read the question?
Things are not always what they appear to be speech again.
The clue is in the question.

Re: Daihatsu diesel generator troubleshooting

On smaller stuff Cats /Perkins Cummings / Volvo etc you can measure each and every cylinder compressions within minutes by not removing anything whatsoever on the engine to be tested. 24v 12v engines. Introduced to me in approx. 1980 and used it regularly since. Not cylinder leakage tests but straig...

Re: Daihatsu diesel generator troubleshooting

I understand this to be a dead engine compression test has been conducted here and that no. one cyl. Is lower than the rest and you want to determine why? My take would be the first check here is to check the tappet clearances on no. one cyl. A tappet with no clearance or too tight a clearance would...
