CDI 511-9773 (DVA) Peak Voltage Adapter and Resistance Chart

 

NOTICE: The resistance readings given are for a room temperature of 68 degrees Fahrenheit. Higher temperatures will cause a slightly higher resistance reading. DVA readings should always be taken with everything hooked up.
The CDI peak reading voltage adapter is specifically designed to work with FLUKE AUTO Digital VOLTMETERS. This adapter will simplify the testing of electronic Ignition systems, stators, and sensors. The peak voltage readings will be approximately the same as any other peak voltage meter, and the specifications in the test manuals can be followed without any major problems. STEVENS INSTRUMENT accessories for the CD-77 peak reading volt meter, SA5, SA6 (CDI#511-9756) and PL88 (CDI#511-9775), along with the CDI 511-9770 piercing probes are highly recommended for use with this adapter.
 
Instructions: Plug the adapter into the Fluke digital volt meter with the rib (+) plug in the (v, Ohms, *) jack, and the other plug in the (COM) jack. Set the switch on the Fluke meter to the DC voltage setting and connect the probes to the test points to be measured. This adapter will automatically compensate for polarity and all readings will be peak voltage. The Fluke meters are auto ranging and will read the proper voltage level without changing ranges. See the attached list of readings and instructions for testing most Mercury Outboard Ignition systems. Other ignitions can be tested if the manuals give peak voltage readings or is you test a known good Ignition system.

Notes:
(a) = Blue to blue/white may read 600 W for some Rapair/CDI Electronic stators
LS = Low speed
HS = High Speed
1. Most Mercury Outboard Ignition systems use a red Wire and/or red/white stripe for the high speed charge coil, and blue and/or
blue/white stripe for the low speed change coil.
2. 3 & 6 Cylinder. '76-up charge coils are measured from ground (black Wire if present) to red and blue wires.
3. 4 Cylinder. '76-up switch Box, charge coils are measured between the wires (blue to blue/white, red to red/white) with no
connection to ground
4. CDI and Rapair Stator/triggers will vary from the original charge coil readings specified in the manuals. all the readings
       should be consistent and no varnish leakage should be visible

8. Batter CD triggers: 393-3736 measure between black and white wires / 332-4797 measure between black and blue wires
9. 2 Cylinder. triggers read between the two Trigger wires.
10.2 Cylinder. '77-up with 339-7452 switch Box, check from black/white and black/yellow to ground. Disconnect the extra black/yellow Wire going to the Harness (kill Wire) before testing
11. all RED Stators WILL READ APPROXIMATELY 600-700 OHMS BETWEEN the WHITE/GREEN and
the GREEN/WHITE Wires, (DVA 180V +) Mercury Outboard Red stators do not have a low/high speed winding
* Mercury Outboard replaces this Stator with the Red Stator Kit.
