Starter Brass Screw, For Negative Bat Lead?

Post by Wee59dexta »

Has anybody seen a brass screw situated on the Starter Motor here before? The negative battery lead was fixed here, but on other dextas it seems to be at the front of the starter......


Just wondering if this is original.

Thanks again.

Is your tractor negative or positive earth?

Looks like an attempt to get the volt drop to the starter a bit lower.

Ben, the tractor was previously wired negative earth with an alternator, but since restoration ive fitted an generator. can anyone explain why this not is here and why previously the battery lead was attached to it?

I hope to wire the tracor soon, positive earth, so what do i do with the starter?

thanks again. (Sorry i aint been replying, ive been in hospital)

Positive ground with an alternator is a bit of a challenge!

Given you are converting back to the standard configuration with generator and +ve earth, suggest you follow the standard wiring diagram downloadable from fordson-dexta.de (workshop manual electrical system).

Hope you're feeling better!

If your using a gen then its easy enough, simply swap the bnattery round and re-flash the gen field winding.

Hi, this brass screew place is unusual on dexta starter,s...I have not seen it on those. But if someone has moved the "inputbrasscreew" onto side of the starter ?? it very well still can funk...but this indikate again that someone has rebuilt this point. The screew have also to go through the starter from the brushes and be insulated from the ground of starter. - It also can very well be some groundscreew??? (then it will not be conected with the brushes...) - Take that look on it. - The starter will not affect on minus or plus... Anyway you have to check this starter, and look good on it, test and measure it. When you open up your starter for measuring you will also check the brushes - kommuntator - insulation - and manuel parts as bendix a.s.on.

Checked the date on this starter - Its stamped October 62. Our tractor is 1959, so this is clearly not the original.

Is this the proper dexta starter motor?

That date is interestingthat you found on your motor, where on the starter motor did you read it? I was not aware that there is a date stamped onto the starter motor.

When I cleaned the starter, as it sits on the tractor at the top, below the Lucas stamp, theres the model number, and then the numbers 10 62.

Thanks for that information I will have a look on my starter today.

Good luck with the repairs on your starter, it does get frustrating seeing good money spent with no progress.

Just a question about this brass terminal on the side of the starter, are there not terminals on the front of the starter?

Opened up the starter today. The bendix is moving freely, the cummutator looks alright but the brushes are fried. The original terminal post is not connected to anything. The existing terminal which must be a redesign by someone cracked and shot off. When the tractor started there was a bang, and the starter lead was hanging loose by the side of the tractor as a result. Noboby seems to know why this occured.

Im sick of this starter and therefore i'm on the look out for an untampered, original type one. I'll be looking no more at this starter, because i'm not prepared to travel around the country, wasting time and money looking for answers on a starter which is a piece of crap! :curse:


Cheers for your interest.

Hi we59dexta, gretings for you decision to throw it away... Mybee it can be rebuilt but it is in need for total measure,d. (The field wirings has not to be shortcut,d at any time) and the ancor and communtator need to be OHM,d... so just buy a new one and try it in a bench at first.
God luck
