Description

1949-1952 Chevy 2DR Hard-Top Coupe/Convertible Front Door and Rear Quarter Power Window Kit
Kit includes: 2 front door regulators (left & right side), 2 rear quarter regulators (left and right side), 4 new ACI motors.
Note: Requires diagonal door adjustment rod to be slightly altered for motor clearance on front door regulator
Note: On convertibles, there will be modifications for the rear regulator to be installed. The mounting plate must be bolted up flat. Trimming to bracing required.
You can add a switch kit at a discount.
If you add a switch kit, conduit will be included at no additional charge. If no switches are required, motor plugs
and terminals will be included. If you choose Nu-Crank Switches – consider adding a master switch to control other windows.

Note: Nu-Relics ACI motors are reverse polarity motors and require reverse polarity switches.
See Technical Tips for additional information.
Note:  It will be necessary to trim the metal on the quarter panel for motor clearance. This will allow the regulator to bolt up flush to the panel allowing the regulator to function properly.

New ACI Motor AMP Draws
No Load amps Low Load amps High Load amps Stall amps

ACI Motors are Reverse Polarity
This means that the ground for the system must come out of the master switch. There are 2 poles on the motor – to make it operate,
you must put power to one side then ground to the other side – NOT to the motor case. This will result in the motor turning in one direction.
By swapping the wires from side to side, the direction will change.
Fuses or Circuit Breakers – 30 AMP
Most of our harnesses will come with an in-line 30 AMP fuse. If you prefer, a circuit breaker will work too.
You can hook your windows up to a varity of different power sources.
Some options are:Straight to the battery (Windows should not have any battery draw when not in use).
 Find extra slot in fuse panel – tie in using the supplied fuse.
 Pull power from the key-on side of the switch
Relays
In most cases, you will not need to use a relay to boost amperage to the motors. The switches and wiring we use can handle the amp draws.
If you are using old style 3 pole switches, a special relay is needed to reverse the polarity at the motor. These do not increase amperage,
they just swap the ground from side to side. we have these available (prewired). Call us at 336-699-8949 for assistance.
Grease & Oil
1. On the regulator gear teeth and roller tracks, we recommend using a high temp automotive wheel bearing and chassis lubricant.
NLGI grade 2 is one option
2. Avoid the older soap based lithium grease – it sets up hard in cold weather making the windows harder to move
3. A few drops of light weight oil in the pivot points will allow the Bronze Oilite ® bushings to work smoothly and reduce wear.
4. On fuzzy runs and weather stripping – some 3M Silcone spray can help with break in
5. Use Die-Electric grease or Tuner Lube on all terminals and connections. This protects against moisture and corrosion.
