Power Trim Motor Brushes

Taken apart the power trim motor on my Merc 90 to clean it up and paint it as it was getting a bit corroded. I've managed to break the brushes in the motor. Does anyone know where I can get replacements? They're 9mm wide x 10mm deep x 15mm long (ish)

Had a quick scan on Ebay to see if I could get similar / larger brushes and file them to size. Cheapest similar ish ones were 12 plus all the faffing about so I went to these guys

A.J.W. / A.C.W. Electrics | Car Electrics - Yell

For 15 they're supplying and fitting the new brushes (filed down to fit and soldered in properly), cleaning and reasembling the motor. All in 24 hour turnaround.

Used them before for Mrs's car starter motor repair and can't fault them, really helpful and really cheap!

Grrrr! All sorted now but I've figured why the power trim motor housing had corroded so badly- rubber O rings top and bottom blocking electrical continuity from the adjacent parts so no corrosion protection from the anodes.

Surely this needs to have a small bolt welded to the side of the casing with a second CP cable leading onto it..?

Cheers Jambo. My attempt was a Heath Robinson 'stand clear' contraption. Did the trick though and still going strong. I take personal delight in being able to say I used Mecanno springs, yes you read that right, Mecanno springs.
