(ET) Front Lift Motor for E-20/Wheelhorse C-185

[Klein Robert W NPRI <KleinRW Npt NUWC Navy Mil>]

Well I got my six new Trojan T-105 Batteries installed and wired up the 
lights and front lift motor taps according to the manual.  Off I go using 
the snow blade to grade my gravel driveway... which does a great job 
flattening the surface when dragging the blade in reverse.  Half way down 
the driveway the front strap brakes.  No Problem... I take the strap off 
the rear lift and install it.  Then the 30A slo Blo fuse blows.  So I 
install my last spare.  That to blows.  Uh Oh!  I super clean all the 
contacts, temporarily put a wire jumper in place of the fuse, clamp on my 
ammeter and read 45+ amps when toggling the lift switch. I motor back into 
the garage and put it up on the jack stands, pull the front lift down and 
pull the lift motor off the winch structure.  I then measure the amps 
again... still 45+ amps.  Guess the motors bad duh!.  It's a Delco 
Products, Rochester, NY USA  assembly with the electric motor built by 
Delco Products, Dayton, Ohio, USA, Serial Number 5045631 on
3-39-73.  Not being one to leave anything alone I scraped off the 
waterproofing material and took it apart.  There is an extremely pungent 
odor of burnt electrical stuff.  Armature shaft turns freely in the 
bearings ruling out mechanical failure.  Gear lash adjustments were nice 
and smooth.  Brushes looked OK but I broke the fiberboard mounting plate 
holding the brushes when disassembling it.  The armature looked good.  
Contacts clean and shiny. And for the failure that caused the high amp 
draw???  Looks (and smells) like the internal coil shorted out.

The good news is I was able to use the motor assembly from my rear lift 
and it only pulls 6 amps when running (no load/light load).  What a 
difference.

So,  Does anyone have a spare lift motor they want to get rid of?  Or can 
anyone identify which GMS vehicle right hand side power window motors will 
work?  Any help is appreciated.

Thanks in advance,

Bob
