Headlight Actuator Module

Postby Paul Beech » Sat 28.08.2010, 19:30

Hi Guys,

I could do with some help on this one:

My Driver Side LIght pod doesn't lift and having put the multimeter on it I have diagnosed that it is the power supply leading to the motor.

I think, after research, that it is the Headlight Actuator Module which has blown powering the driver motor.

Problem is this - Where is the damn thing?!!

Also, asdie from reading the associated parts thread http://wikilec.9600.org/index.php/Light ... z_together does anyone have one or a suggestion for replacement except make one / clean contact (once I have found the module!)

Thanks for any help you can give.

Cheers

Paul

Put your location in your profile please Paul - maybe someone is local to you.

BTW it's on the bulkhead! (from the wiki -"On the Elan, while looking at the engine bay, the module sits on the left hand side of the firewall").

And I have a spare!

Ooohhh :wink:

Many thanks for the swift reply Dave.

I will have a look in the morning and let you know after a little WD40 etc :D

BTW I'm in Bromsgrove near Paul Matty's (profile updated to reflect as per suggestion)

Ok Guys,

Don't know if this is bad news or what. The attached photos show that the unit has suffered from high temperature, enough to melt the solder below the chip marked "st a501 165082"

I'm going to try to resolder the part but it looks terminal (pardon the pun!) :(

I will post an update later but I have a bad feeling about this.

I don't know what the possibility of bridging the good terminal to replace the bad but I suppose if that wasn't done in the first place then the second chip will blow as well.

Regards


Paul

I wonder if the high temperature might be due to friction in the various linkages putting an excessive load on the motor?
I would suggest removing the headlamp pods and freeing-up and oiling or greasing everything that moves.

:agree:

My advice would be don't try and repair it as you are likely to do damage elsewhere. There has been a lot of current flowing (look at the oxidation of the tin on the leads and the blistering/de-lamination of the pcb) and the wire link has acted like a fuse so I'd check that fuses C1 and C2 are 15A because they should have blown first.
