Can any one help please I have a electrical fault on the feed control module of my milling machine and am trying to find out the value of the resistor which has burnt out, the control module is a "ERSKINE Rev4 PD-1114-03-B" control box (on a Bridgeport series 1 mill) which controls the table longitudinal feed.

if any one has a close up photo, or a circuit diagram of this its much appreciated...

Here is the crunch all the manuals available that i can find on line, or have got copies of all show the American version which have different circuits.. so it is the English version i am after.

I will paste a photo a bit later

Thanks Mark

I have nice, re-drawn, versions in pdf format which I can send if you PM me with your E-Mail address.

Many thanks are due to fellow forum members John and Ken who kindly supplied me with photo copies of original Erskine data and circuit diagrams just before Christmas which I was able to re-draw and re-dtp into native digital files which print out cleanly.

erskine r6 2.jpgHi Clive

Thanks for your reply, my email is

Many thanks Mark

For any one interested the resistor in question is R6, which was damaged when a fault occurred with the micro switches and one was effectively welded / stuck, so both were being operated at same time. or thats my conclusion, as to the cause,erskine pcb front 2.jpg

Hi Paul

No problem but I'll need an E-Mail address to send the data to.

Alternatively you could sign up with the Bridgeport Yahoo Group and download it from the files section there.


E-Mail and attachments are on their way.
