Retracting mirror motor

Post by TheStinkyHippy » Mon Apr 27, 2015 9:04 pm

So, my drivers side mirror was wobbly and doesn't retract.
I stripped it down, and found the motor was dead.
I ordered a replacement from the details on http://igmaynard.co.uk/bongo/forum/view ... or#p623566

That came, but found it still doesn't work.
I've narrowed it down to the switch inside the motor that stops it when it is fully open/closed.
Comparing it to the other mirror, the diodes are dead.
I get no flow through the diodes.

Now, I am stuck on what to buy..

There are 2 diodes, both the same.
They have a green band on the cathode end, and markings E 5A on them.
I'm pretty sure they are the diode on http://www.g8dhe.net/bwm/bwmanualp.htm?1995/Page_112
under the X17 and X14 switches.

I know very little about diodes.. can anyone tell me what to buy to replace them.. if maplin have them even better.
or it is these? http://www.amazon.co.uk/dp/B00HGALQLY

I would imagine that these rated at 3A and 50Volts will be fine

No you don't need Schottky diodes for this!

Thanks for the reply..

Unfortunately those were much too big to fit onto the circuit board.

In the end I bought 2 of these: http://www.maplin.co.uk/p/1n5817-1a-sch ... fier-ja46a

Good news is that the mirror is back to fully working and retracting, but it is slower than the other one.

not bad though for £10 motor and £1.18 components
