Sir Nibble Posted August 19, 2017 Report Share Posted August 19, 2017 It does demonstrate the difficulties of diagnosing at a distance, the earth was supposed to have been bypassed with jump leads without any effect on the problem which logically eliminates the earth circuit from suspicion, but only it seems if one has done the crocodile clip and clean metal course.

Crocodile clips won’t really give you a good contact for the amount of amps needed to start the engine, and the cable in jump leads are thinner than thin. Reason why I suggested above that a quick test is to use proper cables directly to/from the battery. Link to comment Share on other sites More sharing options...

My experience is mainly with petrol, but I have started large van engines a smaller tractors with conventional jump leads, and a stone flat 3l petrol with £6 'max 1000cc' service station jump leads before now.

mross Posted August 20, 2017 Report Share Posted August 20, 2017 I'm sure crocodile clips are good for a while - i.e. for starting an engine soon after fitting them. But when used for charging batteries overnight in humid conditions, it's surprising how much white powder appears on the terminals. It must also depend on how strong the springs are on the clips - some are fierce! Link to comment Share on other sites More sharing options...

Daniel But you are going through a connected starter battery to do it, the bulk of the amps is still via the starter battery.

MtB Posted August 20, 2017 Report Share Posted August 20, 2017 'Ampage' would be ok, but still clumsy. "Amps is" grates so badly because it is grammatically wrong on two levels. Link to comment Share on other sites More sharing options...

"Amps is" grates so badly because it is grammatically wrong on two levels. Ampage is not goodage because it ain't a word. Amperage (not ampage) is a word which was invented over the last few decades because folk are too lazy to say 'current rating' but I still hate it, probably because it was drummed into me at school that it wasn't a word. Nevertheless it's dropped into common usage so much that it now appears in some dictionaries, although not that of the IEEE: http://ieeexplore.ieee.org/document/4116787/ Wattage is another made up non-word that replaces 'power rating'. (See above link) Voltage is a word. Edited August 21, 2017 by WotEver Link to comment Share on other sites More sharing options...

As above, unlike 'ampage' Voltage is a word, so there's no trouble in using it. By way of example, I could refer to the floatyness of a boat if I so chose. It floats doesn't it? That doesn't however make me correct in inventing a word when a perfectly good one - buoyancy - already exists. Link to comment Share on other sites More sharing options...

And on a related note my kids throughout their childhood used the term "see-through" for "transparent", picked up from skool. Their mother and I disagreed about whether they should be corrected.

WotEver Posted August 21, 2017 Report Share Posted August 21, 2017 For anyone interested in a serious answer to Mike's question of 'why?'... Voltage is the thing being measured... in volts. EMF and PD are also both measured in volts. One would say that the EMF (or PD) of a circuit has a voltage of x volts. Current is the thing being measured... in amps. You are not measuring amperage. Power is the thing being measured in watts... you get the idea. Link to comment Share on other sites More sharing options...

mross Posted August 21, 2017 Report Share Posted August 21, 2017 https://www.merriam-webster.com/dictionary/amperage - note first use in 1888. I have used it over 40 years. https://www.merriam-webster.com/dictionary/wattage - first use 1903. Have you never talked about the wattage of a light bulb? 1 Link to comment Share on other sites More sharing options...
