ree_eric wrote on Sat, 06 May 2017 23:52I have a system installed that I would also like to get working. I have new bearings for the pump. However only one connection at the level sensor is visible, was it a 2 connection with the second to ground? How did this level sensor work? Also missing the speed sensor, could a throttle position sensor work. A thermo sensor would work, anyone know of one that would work? What does the vacuum sensor close contacts for, high or low vacuum? Just about done with the braking and fuel systems now A/C and others...
I'm back...
We are northbound from Bean Station and I have some time so:
The vacuum and speed sensors were a cost reduction (at that time <40ya) from the original that did have a thermocouple switch to start the pump. You can now buy a T/C controlled switch cheaper than a new speed switch. I suggest that you do this. Set it to turn on when you have been on level ground for about 3 minutes and be ready to shut the system off manually if you get slowed down. Even the T/C systems did have a speed switch.
As I recall, the vacuum switch closed below 16".
The tank level sensor was an RF switch because nothing else stayed working long enough to warranty. Even thought the pump will not be damaged by running dry, the marketing people felt that it had to be there to show owners that the system had done all it could do.
I was the last engineer on the program and if you have any other questions, I can try to answer them. Please realize taht the are old memories that I had no interest in keeping.
