Power folding mirrors

I see!

What else are traffic lights for but to sort one's messages and emails?

I though it was a moment to watch life going in different directions! LOL

Don't need to watch can see with a tracker APP on the phone/tablet.

I'm at my wits end with this project! I have now diode isolated the ignition trigger switches exactly as @howie II shows in the diagram in the second post of this thread:

but the mirrors still won't fold/unfold with ignition on/off! I still notice that my DMM shows 12 volts on both yellow common wires and both 528t's are triggering with the ignitiin at the same time.

Any ideas on what to look for next?

I'm also not opposed to bypassing the car switch to fold the mirrors if it's easier to just hook up the 528t's by bypassing it?

Thanks for all the replies and help!

Sorry...heres the thread mentiined above https://www.the12volt.com/installbay/forum_posts.asp?tid=141431

I have tried 1A 50V diodes and 3A 50 PIV diodes.

Only suggestion I have is to use the GWA - output to fold mirrors in and ignition to fold out.

The same applies to all wires when the ignitiin is turned off. Shouldn't only 1 motor side wire show 12V and the other show 0V during opening and vice versa during closing?

Yes. I don't think the switch side wires are resting at ground. Are you certain the pink and blue wires are the actual motor wires, and are AFTER any module, memory module, body controller, ect? Can you make the mirrors move by grounding one motor-side wire, and applying 12V to the other? If so, you could add a relay in the opposite wire to supply ground when the timer is active. Adds some complexity, but would work around the switch side wires not resting at ground, and retain the OEM switch. Another test would be to temporarily connect the timers' brown wires to ground. If you can make the timers fold the mirrors with this configuration, it confirms that the "switch side" wires are NOT resting at ground. This test will only be valid if only ONE timer is activated at a time. (You indicate both timers activate simultaneously. You need to figure out why this is happening, and correct it). Perhaps this fresh input will help. Lots of chatter in this thread.

Thanks DAVE it does help me, very busy at the moment and I missed the part about both activating at once. WHAAAT? Also about resting at ground, since they are DATA to door module to mirrors you might be right. Only ever seen rest on open on the REAR door locks on London Taxis, the fronts were NEG switched. LURCH what GWA?? Have I missed some part about there being an alarm in this thread? PS Lurch if there was an alarm or RS I'd have used aux outputs linked to arm and disarm as timed circuits with standard relays and forget 528 and 535, unnecessary expense.
