Borg Warner/Velvet Drive 72 - Question about pressure sender port
Where exactly am I supposed to connect the pressure sender? On the diagram in the service manual, there are three ports, and I have attached the mentioned diagram here. One port for the oil to the cooler outlet, one for the mainline pressure tap and one for reverse clutch pressure tap. So I have attached the hose to oil to the cooler outlet, I have attached mechanical pressure gauge to the reverse clutch pressure tap, and I have attached the electrical pressure sender to the mainline pressure tap. Mechanically, everything runs perfect (gearbox is new). When in reverse I do read the pressure on mechanical gauge, but in forward there is no pressure on electrical sender (no reading at the gauge). Sender, gauge and the wiring are OK (checked twice). Am I reading this diagram wrong, should I connect the sender to the cooler outlet? Where am I mistaking?
