Why would anyone listen to the mechanic........ they were perfectly fine until they weren't
Is it time?
Is this bad? (Green deposits on negative)
The switch was not designed to carry that amount of current.
I am sorry...did you see the cables? Do you know what engine I was working with? Your profile says your in Cape Cod.. Are you actually in South Freeport standing over my shoulder?
The switch is designed for 250 amps continuous and 350 amps intermittent. Melting plastic is the result of too much current flow thru the switches contacts. This would happen even if you had 4/0 cable installed installed on the line and load sides of the switch.
Melted plastic is due to heat. Two possible causes, too much current, or resistance in the contacts. They can corrode over time, you can also draw an arc across the contacts if switched while carrying a load, resulting in resistance in the contacts.
In any case the cables...that were bad have been changed, and obviously the switch has been as well.
Customer is happy. I am happy.
See we do agree, customer is happy and issue is resolved.
Well with the starter draw of a Yanmar 1GM being well below 360 amps I wouldn’t say I agree. I figured no point in arguing a point in which couldn’t be proven either way. Is kind of like arguing what came first the chicken or the egg.
This is the second tread that you have kind of “trolled” me on....but I will give you the benefit of the doubt and move on.
Chillax ya’ll. Don’t heat up, you might melt like the switch did. Trolls...
Oh I am chilled. Water under the bridge. Hopefully when the tempo slows down at work, and at home I will be able to post more. This as been the weirdest and busiest spring I can remember.
I am glad you are busy!!! Rock on! I guess we need more love in this world! I wish people kept the trolling on the fish!
No biggie. He may not have been trolling. It just seemed that way. He is a ABYC master tech so his opinion matters.
Jerry I think your tag should lead with Jedi or some shit like that! lol
