Okay. I replaced the LP. Not remarkably impressed so far. I did no bleeding, so I was not surprised when it took a bit, and some smoking to get going. I was not impressed AT ALL by my initial results. Then I took it down the road a ways, and it is definitely better. Better power, smoother when running... but it still isn't quite right, not like is has been for over 3 years. I am still inclined to think the problem is the voltage driving the LP. I did not change the OPS... took a look and said to myself: "Self, shall we tackle this?" Upon this query, self said" "No, hell no!"
Now then, I have a source for battery power, I have no wiring diagram, and I want to modify the circuit so that the trigger voltage is "key switched 12vdc", and the relayed voltage is 12vdc, from the battery, SO:
1st, What color wire do I cut for the trigger voltage? My vision ain't the greatest, so I will do better with a wire color, than with a pin number.
2nd, where do I find a switched 12vdc nearby?
3rd, what wire do I cut for the battery supply voltage?
I THINK the purple one is power to the pump, is that right? That is one I should not have to mess with then.
I appreciate the help. I have to use the truck in about 2 weeks to move a little crippled up (even more than me) fellow about 15 miles. If I can get the truck running right, then I can use the big trailer, and cut down the number of loads I have to make.
Yesterday was not a good day. Getting up and down during the LP change process had me stiff. Then, just to add insult to injury, when I gassed the mower so I could mow... I grabbed the wrong can, and put in some #2... yep, diesel. Oddly enough, the mower did not want to run on it. Who would have thought that? Got that taken care of, did the mowing, and by then I had topped off the batteries on the truck (if they are down even a little, it does not like to cooperate). She fired up with lots of smoke, white smoke. Let her even out, and took her down the road. Better, but not quite right though, hence the above questions.
