Warning horn beeping

Re: Warning horn beeping

John/sschefer,
Oil line and 3 gallon oil tank one year old and in good shape. Oil reservoir on motor full with enough pressure to flow out if cap loosened. Drive gear on crankshaft good. No apparent wear or malformation of worm gear & small verticle gear in pump but ran the volume check again (using pump outlet tube disconnected above the check valve) and still get only about 1/2 the volume listed in manual for 3 minutes with and without link arm.
Double checked electrics - could not get reading from wire to #2 coil at coil or at junction box. However I did get 12 v on white from vro to oil sensor and 5 v on oil sensor blue/white to vro as manual specifies. Even if there is a missing pulse train, that is a problem with alarm & it doesn't negate the fact that the pump is at very reduced volume. Can the rotational sensor detect resistance and/or pressure differences in a worn pump???? I will probably take to shop this week as they have testers that I don't have but wanted to do some investigation and homework first - shop has reputation; if you get my drift.
Anxious to get after those salmon in a couple weeks.
Thanks,
Bill

If you can't get a reading on #2 with a DVA, that cylinder must not be firing. The alert module doesn't care which cylinder it gets the signal from. You can move it to another cylinder, especially for troubleshooting. That is probably your alarm issue.

On the oil pump volume test. Are you sure the RPM is right? It is possible for a pump to deliver low volume, but it rarely happens.

If the volume is actually low, the pump needs to be replaced. It is not considered a serviceable item, but I have an electronic manual with about 8 pages on disassembly, inspection, and reassembly of it. If anything metal is bad, the pump is junk, but all the o-rings and gaskets can be sourced or made.

Usually, this is about the point where the decision is made to rip the whole oil system off and premix.

hope it helps
John

Rpm's were at 1500 per the troubleshoot guide.

Okay, will move alarm to different cylinder to eliminate or verify alarm problem, then will decide on replacing pump vs premix.

If moving wire shuts off alarm, then I assume coil needed?

It has been trouble free for 13 years so it has earned a few parts.
You and sschefer should come catch a salmon or halibut with me sometime.
