Setting the stage:
- Early season, new battery
100Ah, 12V, 690 CCA
- Operated 8 or 9 sails
since install, no trouble
- Two weeks ago, I had a failed pinhole leak in the lubrication oil
tubing that resulted in complete loss of oil
. Fortunately, I was in the fairway and just quickly made the slip and shutdown. Fixed this the following weekend. Motored out no problems. This was two weeks ago.
- Today, visited the boat. Decided to change the fuel filter
and re-tension the belts. Quickly did this in less than an hour. Bled the system of air.
- Went to start the engine
, key on, ignition alarm
came on like normal, pressed the start button. Nothing. Would not even turn over.
- Started checking voltages everywhere. Starting with battery
. 13.2V, seemed fine. Went to key switch, roughly the same about 13V. Went to the Start button roughly 13V on primary, but dropped to about 3-4V on output.
- Thought maybe I had a bad Start switch, so I changed it out with my spare. Checking continuity, both switches were ok. After installing new switch with no positive result I started looking at the starter.
- Went to the starter and found the white wire had rubbed raw (from vibration over the years) and was grounded. Fixed this. Now had about 9V at the terminal of the starter. Main voltage at the positive terminal of the starter was 13.2V. Negative terminal seemed fine.
- Double checked tightness of all terminals, cleaned wiring
, just in case I had an external ground somewhere.
- I even tried pulling the battery and charging
it for about an hour, just in case it was the battery.
Things I did not try:
1. Pulling the starter OFF the engine
and see if it turns over.
2. Disconnecting white wire from starter and see if I had a full 13V.
Any suggestions? Experiences?
Appreciate the thoughts.
