Re: Need to drop voltage to a motor?
I'm not to cuncerned on load due to the limited use of the motors used only for a second to open or close. I've tried about 10 differant volt ranges and the 9volt seemed to have the right speed to mock the org vacume open rate. You could use the factory control module, But I found it a tad to quick, Hope know ones has fingers near the door when it is shuts at about 100mph. With the choice of 9volts I also won't have to deal with broken bent or lost parts. As for how I wired mine up simple two relaysmain power from batt, to fuse make a Y feed one to 85, 86 to switched gound, main ground to 87, 30 to motors on both.
2nd realy same as about except a swap on to poles 85 goes to switched ground 86 is now input hot. I used a ground switch in place of a hot switch cuz I'm lazy. With this realy set up You can go hot to open and the 2nd relay will be off and connected to dead ground, you can close and your open hot falls dead to ground and your ground goes to open hot, quick easy rev of poles. You can get a vett headlight switch and it had switched neg poles on them to complete the install I'm right at $125.00 out of a junk yard. If you need a few pics let me know
