CDI 193-4476 Installation And Troubleshooting Manual

This unit replaces P/N's: 18-5827, 584476, and 585001.
Warning! This product is designed to be installed by a professional marine mechanic. CDI Electronics cannot be held liable for
injury or damage resulting from improper installation, abuse, neglect, or misuse of this product.
DO NOT USE A MAINTENANCE FREE, AGM, OR DRY CELL BATTERIES AS THE USE OF THESE TYPE BATTERIES WILL VOID
THE WARRANTY AND CAUSE DAMAGE TO THE RECTIFIER/REGULATOR, ENGINE, AND/OR THE STATOR!
NEVER DISCONNECT THE BATTERY WHILE THE ENGINE IS RUNNING AS THIS MAY DAMAGE THE REGULATOR/RECTIFIER.
If the boat is equipped with a battery switch, make sure that it is a make before break type.
1. Disconnect the Negative battery cable.
2. Disconnect all of the wires from the old Voltage Regulator.
3. Remove the old the Voltage Regulator. On some engines, it may be necessary to remove the flywheel first.
4. Thoroughly clean all ground connections and the Voltage Regulator mounting area.
5. Connect the new Voltage Regulator to the Stator. Ignore any stripes on the Stator as the new Voltage Regulator does not require the
Yellow wires to be connected to a particular Stator wire.
6. Reconnect the Negative battery cable.
BATTERY CHARGING ISSUES:
1. Regardless of whether the charging issue is overcharging or not charging at all, the #1 cause of all charging issues is the battery often
due to improper style and/or charging neglect. #2 is the battery's connections. #3 is the Voltage Regulator. #4 is the Stator.
2. The recommended type of battery for outboards is a single (NOT more than one) 850+ CCA dual purpose or cranking/starting non-
maintenance-free battery.
Non-maintenance-free batteries (lead-acid flooded cell; has vent caps on its top) have heavy, thick plates. They're ideal for outboards,
3.
where batteries are commonly drained by accessories while fishing, etc. when there is no charge applied to a battery while the battery
is in use. Its heavy plates can withstand constant discharging and charging. These batteries have much more reserve time and are
much more suited for this behavior.
NOTE: Some Maintenance free batteries will have vented caps on top. When in doubt, change the battery to a non-
maintenance free type.
4. Maintenance-free batteries should NEVER be used in an Outboard application. A new, fully charged maintenance-free battery may
work fine at first but their life span is dramatically shortened due to the constant charging and discharging. This activity will cause the
cells to become weak, and/or the cells will become dead. When this happens, the battery is unable to accept a full charge, thus putting
the Voltage Regulator at extreme risk of failure. Therefore, maintenance-free style batteries commonly cause charging issues shortly
after installation.
5. Check all battery connections, particularly at engine ground. Make sure that all connections are tight and free of corrosion. Do NOT use
wing nuts as they tend to loosen over a period of time from vibration. A loose connection WILL cause a premature battery and/or
Voltage Regulator failure(s).
6. If there is no change, try a single (NOT more than one) known good fully charged battery that is 850+ CCA Dual Purpose, or a
cranking/starting battery that is non-maintenance free. Make sure the battery is a lead acid flooded cell battery (has vent caps on its
top).
7. Measure the DVA across the Stator's Yellow battery charge wires, while connected to the Voltage Regulator. At idle the DVA will
normally between 8-25 DVA. If not, disconnect the Yellow wires from the Voltage Regulator and retest. DVA will normally be 17-50 DVA
at idle. If the voltage is low, the Stator is possibly faulty. Perform a visual of the Stator for browning and varnish dripping. These are
signs that the Stator has overheated. If the visual inspection shows any of these signs, replace the Stator.
