taps killing the boat...

[BobbyD]

The grounding wire was exactly my problem.

believe it or not it was one of my major ground wires. My former dealer (they are out of business now...Wonder why!!!) missed this small issue during de-winterization. My problem was exactly the same. Move taps down and it would shut the engine down and start the loud beep.

I had the two batteries so I guess it would still let the engine start.

Good luck with he troubleshooting.

My ground wire was not properly crimped at battery terminal so I had weird issues at weird times . I went to listen to the new Pro 60's and no music no lights horn bilge nada nothing

Battery cable had pulled out of battery neg terminal causing intermittent power connection and other bs. Boat must have been a Friday boat $ 3.99 and a little surgery and cable not properly terminated and has not failed since To clarify this was factory ground connection.

It still amazed me that it ran well the first couple of hours of time we went boating but once the yellow label slid down the cable thus no more ground. Some basic trouble shooting the use of a multimeter and basic set of tools for the boat and got done

My ground wire was not properly crimped at battery terminal ....

One of the first things I did when we got our boat was to solder every crimped connector I could find.

To troubleshoot any farther you either take to dealer or a shop you trust or contunue to solve your self.

What yo need yo inverst in to do more trouble shooting is oick up and in-expensive multimeter so that you an neasure voltage at the pum, from the taps switches ground to battery ground, volateg at the taps pump when trying to go up and down.

What you are looking fo is a voltage loss. Ther suould be very little or no volts from taps gtound to battery ground. if there is voltage then you need to trace the connection and use the resistance function of the meter to see how much resistance there is from switch to battery and then backwards from all points in the circuit to where the resistance is higher.

To fix this you need a basic understanding of electicity.

Have you in trouble shooting diconnected the wiring to the pump and then while moving paly wil taps switch. If nothing happens the I would try connecting pump to battery and isolate and taps connections thre the boats harness. If the pump when disconnected fron boat wiring and when it is connected directly causes the boat to shut down I would suspect the pump as the culprit here.

How many volts across the battery do you read while boat is running and then when pump actuated. If the voltage at the battery goes down beolow 12v then the pump is probably culprit

This link might help. It shows wiring for an 07 30V but the info will be similar on your boat as far as taps wiring. Do you know any one that understands electrical circuits that could help? Page 2 of the drawing in upper right section has th taps pump wiring. It seems that a relay is in thr circuit so that might be a good place to start checking voltages. Unfortunately the relay does not show me detail as how the relay is wired to pump222
