HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

This is what you need...

911-615-109-01
Multi-purpose 5-pin relay

I bought a cheapo one from Pelican; cost is $14.

I also posted some info from when i hooked up my 914 motor which you may find helpful.

Ok, another question (or three):
I'm using 914 motors on both side. Do I still need to use the diodes?
If so, which wire do the diodes go on? 12v+? Triggers?
And do I just run/splice wires over the second motor in parallel?
Thanks-

You will probably still need the diodes as the 2nd motor piggy backs off the wiring.

I am not sure how the motors are wired on the 914 but i suspect each motor has its own circuit, they dont piggy back so they dont need them.

The diodes have to go on the two trigger wires, in the direction of the 914 headlight motor.

The wiring diagram here shows diodes on both of the command lines at both of the motors. It looks like they're external to the motor housing by the way they're drawn, but mine don't have any, so I'm thinking they must be part of the car-side harness. Both motors are tied together on the same command circuits.

Ok, so I got both motors cycling up and down when manually connecting the appropriate trigger wires (with diodes), but the motors do nothing when all wired up and I turn on the headlight switch.
Any ideas RE what I'm doing wrong?
At the moment the only thing that is wired up for this test phase is the motors- the headlights and other front end lighting are not hooked up yet, and I only have one 914 relay (I've been switching it back and forth to test). Don't think any of those things would affect the motor(s) function, but . . . ?

Have you checked the fuse?

Yup Wink

Don't think it is the switch either, since it used to work fine.

When I power the headlights up with the trigger wire, they do a full cycle-
They don't stay in the up position. They go up and back down.
Is that what they should be doing? I was thinking that the switch would keep them
"Up"/in a energized state, but maybe that is a flawed assumption-

Totally stumped-

Do you have pin 87a on the relay grounded? It's possible they're just overshooting and then completing the cycle.

The diodes are used to prevent the issue you mention, returning to closed. Picture or diagram of your wiring?

Bringing this back up...sorry

Where and how do you cut the headlight bar? I have the 914 motor sitting on the work bench.

Thanks if there are any pics too!

1 page back, you can see where the bar has been cut off of the pivot.
