Stick in the Fan

[MossRoad]

I'm riding a train to Montana, a rental car to Jackson Wyoming, and then return with a couple of days in Minneapolis. Maybe the PT will heal while I'm gone.

Sound like you're going from a bad ground to good ground.

To all you electricians out there, a good ground today is not necessarily good forever. Corrosion will eventually set in and weaken your ground. Screws/ bolts need to be re tighten, re-solder if necessary, and the same goes to the crimp connectors, replace if necessary. You may have to add extra wire to prevent the tension from weakening your circuit. Correct fuse, correct wire size, are all important. With a volt/ohm meter, most problems can be isolated and fixed. There are some electronic ghost out there that will perplex, [ to disturb mentally ] the human mind, one day it works and the next it don't Go figure. It would be hard to tell you how many black boxes we have written up as bad, only to have the electronics shop say there is nothing with it.

These are just some observations I have made over the past 68 years. Not that I cared a lot about this as a kid, but after that, working with Navy electronics, etc.

Last week I leveled some dirt for my brother with my pt 425 and noticed the oil cooler fan didn't come on when I thought it should, so I checked the fuse. The fuse was good but I noticed that when I moved the fuse holder to put the fuse back in that the wire on one side had come loose. That is the second time that has happened and again for the second time I set it in my mind that I am going to replace that fuse holder with a better fuse holder. I hope I remember to get a new fuse holder the next itme iam in the parts store, but I will probably forget again.

I have replaced both of the fuse holders on my PT. Pretty poor quality.

I am thinking that somewhere I saw a small 12 volt circuit breaker that if it kicked you could manually reset it instead of having to have a fuse, that is what Iam going to replace mine with if I can find one of the right volt and amp. rating. I think that would be a better setup.

maybe something like this:

Thermal Trip Circuit Breaker

Or you could try these;

High Ampere breaker

Mid range breaker

All splash proof, manual reset.

All the best,

ponytug-
great site, bookmarked it for later. Dfeinitely better prices (50%) then West Marine for their electrical gear.

Of interest to me was the circuit breaks that plugs into a spade-type fuse holder.

At $2, they would be an easy short-term solution.

One caution on the automatic reset breakers is that you can drive around for awhile with the breakers tripping and reseting. Some of the automatic ones trip and stay tripped as long as they are powered up. So YMMV. I prefer the manual reset versions- then you know that they have blown.

All the best,

Peter

I would only want to use one that you had to be manually reset. I wouldn't want to have to shut the machine down to reset it nor would I want one that would reset itself automatically. If it kicked the circuit breaker I would want my attention on that circuit when I reset it so if there was something wrong I might catch it then.
