Vac switch installed
I finally installed a vacuum switch to run the power brake system.
I shot video of the installation and will do a video about it next week.
Basically, the vacuum switch turns the pump on and off (but only when the key is in position) to keep vacuum in the vac flask up to a pre-set amount.
If the vacuum drops below that, the pump turns on to bring the vacuum back to that number.
Right now, I have it set to run the pump if the vac gauge reads below 10. For example, right when you turn the car on, the vacuum automatically powers up from 0 to about 12. Then, while driving, it will always return to 12 anytime it drops below 10.
