Not sure this will help.
But I guess anything could happen after connecting a ProTrack to a mains supply.
I did a few years back accidently plugged my ProTrack Scanner into a 12 V.D.C adaptor, should be 5 V.D.C.
I put all the details of how I repaired my Scanner on this Forum back on 25th October 2019.
The ProTrack has some isolated D.C. supplies, might be worth checking them.

Last post by Paula Silva - June 15, 2025, 11:36:13 AMThanks for the tip, CWSmith, I've checked them all, replaced some resistors and a reed relay but it hasn't improved anything. It feels like the current inrush reached one of the analog/digital IC's, that's why I'm asking for more help...

Last post by CWSmith - June 15, 2025, 11:16:59 AMThere are relays and range resistors that get damaged when a strong voltage is accidentally applied. Do a visual inspection to see if there are burned traces or components.

Out of Production Hardware / ProTrack I model 20 problem
Last post by Paula Silva - June 15, 2025, 10:41:18 AMHi all, and greetings from Portugal.
I have a "small" problem with my ProTrack I model 20: Since his probes and my multimeter's probes are absolutely equal, I have done one of biggest mistakes on my workbench: sent 220V AC inside its channel A, and now it shows a vertical line. Fortunately I still have channel B working, but the "SCAN" function is not working anymore on both channels, although the "ALT" and the "A+B" functions are working fine.
My ProTrack's serial number is KJ3-01733 and it has (obviously) the KJ3 firmware.
Any help from anyone?
Thanks in advance.

Last post by admin - June 10, 2025, 01:33:33 PMHi Feridun93,
I was digging through some archives and found notes on that transformer.
Primary Winding Pins 1-2 : 100T #28 wire
Secondary Winding Pins 3-4 : 77T #28 wire
Secondary Winding Pins 4-5 : 173T #28 wire
Secondary Winding Pins 5-6 : 126T #28 wire
Secondary Winding Pins 6-7 : 152T #37 wire
Secondary Winding Pins 7-8 : 1232T #37 wire
Each wire terminated to corresponding pin with 3 wrap minimum.
Hope this helps!
James, the transformer in the 5100DS is not the same as the one in the 200. I was able to determine a unique part number of each transformer which would indicate there is some difference in their design.

Did the Tracker 5100 DS use the same transformer on the Analog PCB that Feridun93 is wanting.
I don't know why I got this Tracker on EBay, complete waist of money.
The Analog PCB (Tracker range generator) was missing. And I see on the diagram on the Huntron DVD it has a transformer (T1) on it.
Only good for spare parts if anyone wants one.

Last post by CWSmith - June 10, 2025, 08:37:05 AMAll of the transformers used in older Trackers were custom built by Huntron so off the shelf parts probably won't work.
