light pod motor rebuild

light goes down with motor , but not come up. any ideas thanks

This will get moved to the appropriate technical section, no doubt.

The problem most likely lies in the swithces in the end of the motor under where the spindle comes out. It's a common enough problem to have been covered a couple of times on the forum. I suggest you use the search function to find them then you will get all the low down on it. Should be easy to fix.

I did the search and here's a link Headlight lift problem discussion.

And another one More headlamp lift woes.

And another Headlamp stuck.

I suppose the moral of this story is that, if you have a problem with your car, you are most likely not alone and someone has a solution.

Hi Manny, I will be fixing a pod motor over the break - so I will race you, ready set, go!

Good links above.

All fixed - at 1.5 months to complete, the longest race ever

(wonder if I still beat Manny?)

Dont drive it when its dark out.

Looking to rebuild mine as they bounce as you drive down the road....

Checked the balljoints on the rods but the play seems to be within the motor...

Seem to remember someone posting about rebuild kits for the motors.. i.e. new gears for inside to eliminate play!!!????

Any ideas... Wayne your probably best for this one!!!!???

Cheers

Consider testing the motor in place before assuming its the motor.

I have an S1 but if your 84 motor is designed to spin in one direction like the S1/S2 motors, then I would try feeding the motor +12 volts directly (without the switches and relays) to see if it operates. If the motor goes down, it implies that the motor is operating ok and its just that the power route to the "UP" circuit has a problem.

If it does, I'd suspect the headlight relays first and microswitches next.

As I said, this is valid if the motor operates like the S1/S2 motors and rotates in one direction.

I didn't check any of the links, but if you need internals, the motor is the same as on a TR7, save for a few interchangeable parts (but the worm and worm gear are the same).

For the U.S. guys, a good source of parts motors is Scott Harper at Team Triumph in Youngstown, Ohio.

I got recon ones from Robsport (clicky clicky) I think they were about

You definitely need a wiring schematic as a road map to the head lamp lift motors and relays.

When my Esprit had this trouble, I had to disassemble the the motor assembly and replace a blown diode

that toggles the motor relays and a large "in harness" diode that separates the Hi Beam

switch from the Hi Beam flash to pass switch and the Motor direction control relays (this diode is in a black

tube near the left front wheel well...you might want to smell this component).

The harness diode can be replaced by a 30Amp Silicon Rectifier (I used a GP30G). The diodes

in the headlamp gear machanism can be replaced by anything in the 1N4001 to 1N4008 1A Rectifier

diode series. These parts are available from almost any electronics store.

It took 4 hours to debug, 1 hour to replace the diodes in the LF lift motor mechanism.

I'm not sure, but I think the Lotus Esprit lift motors and gear are the same as those in

the Triumph TR7/TR8...they certainly look the same.
