Linear Headlight motor Success! (Page 2/5)

Ok, so I've not read well but I'm assuming none of the fancy wiring or modules would be needed, this could be run off standard relays on the actual headlight circuit?

Ignore the Orge, he means well I'm sure but he's got to find reasons to object to everything.

I did not have to run any extra wiring. The fiero already is set up to reverse polarity. Just wire the down blue wire and the grey wire (on the passenger) side together and the green to the up wire on the linear motor. I'm still considering mounting the light to the door itself and just lifting the whole thing. That would eliminate the extra space and mechanical complexity. The motor wouldn't even have to be attached to the light door. Just push it up.

There is room in the front of the fiero to attach a torque tube to run both lights but I worry about redundancy. As designed you usually at least get one light if something fails. I suppose you could put a pin in it so it could be raised manually.
Regardless, this does show a linear motor can perform the function and be quicker than original design.

That's actually a great idea....the arm attaching to the tube could have that extra pin link hole for simple manual up/down if you had linear actuator failure.

The linear activator is really a great idea that you have come up with. This might be the ideal replacement solution for the troublesome 84-86 headlight motors.
As for the concern with jamming , causing damage or a fire, you can just fuse the power line. If it somehow jams, the current in the supply line rises and the fuse blows; no harm done.

It blows the Tail fuse if overloaded as it is currently. Adding inline fuses might be a good additional precaution...

In order to increase reliability / decrease wear, maybe slower is better. I wouldn't be too concerned at the speed they currently move.

I like the slower speed of the actuator powered headlights. The OEM setup comes up fast sometimes with a clunking sound. The actuator system appears to operate much smoother. The only drawback might be that it still uses the complex Fiero system of relays and modules. IMO a problem point for reliability.

DL your video and sad news...
Gen2 w/ New Cardone Motors are way faster that that.
Count the frames... Video is 30fps(Exact 29.896fps)...
Yours is ~ 51 frames, ~ 1 and 2/3 seconds, to have both doors open.

Is under FMVSS and most states rules that allow 3 seconds But...

From my Dash Cam data posted last year, Gen2 is 20 frames, 2/3 of 1 sec, to open. Is so fast that measuring motor volts/amps is very hard because most digital meter don't update the screen fast enough. Even most analog meters won't read fast enough. Need a meter w/ hold or chart functions or storage Oscope.
OEM Gen2 motors was also under 1 sec to open, OEM Gen1 was a little slower then Gen2 but don't have video to count frames for them.

Someone else can upload to YT. I not creating YT media for this.
