Re: Speedo inop on starcraft
I don't remember the air pressure, whether at 100# or something like 40. If I knew the #/sq in of water pressure at say 30 mph and the square inches inside the meter chamber then a swag might be closer.
I think what I did was to stick the air chuck on the rear of the speedo and just bump it (quick shoot of air) looking for the needle to deflect. Figured I could get on and back off before it hurt anything and as I recall it worked ok.
If the meter is made out of zinc, I have found the inside corroded sometimes and if the corrosion is bad enough could stop it from working. Another test of the meter is to disconnect the water line while running and see if water is coming out of the hose at the rear of the meter. If so, sounds like a meter problem, if not, pickup or distribution problem.
HTH,
