trouble starting engine when solar panels are working
When my solar panels are charging (~14V) and I try to start the
engine, it basically acts like the batteries are dead. No turnover, just hear the click of the solenoid. I unplug the solar panels and it starts right up? Any ideas what could be causing this? Wierd. Tom |

I unplug the solar panels and it starts right up? Any ideas what could be causing this? Wierd. Tom It's obvious that you have your wiring screwed up. In order for your starter solenoid to work it must have two working circuits. One is the one that makes it click (the electromagnet that closes the high amperage circuit). The other is the high-amperage circuit itself that runs the starter motor. Both need good clean grounds - the low amperage circuit especially. If it clicks it's probably working properly. That means the high amperage circuit is non-functional when the photovoltaics are connected. What could cause that? Probably you have it connected to the regulated side of the charging circuit. You need bus bars and heavy duty buss bars at that. All your positives need to be connected to the positive buss bar and all your negatives need to be connected to the negative buss bar. If your photovoltaic charge controller has a high voltage cut-out you need to be sure it's not cutting out the circuit to the high amperage side of your starter motor. Wilbur Hubbard |

That's got to be one of the funnier things I read here for quite some time. I have some advice. The advice is please shut up if you've got nothing to offer but ignorance and stupidity.

Perhaps if we had more info about the circuit.... are they connected directly to the batteries? do they run through something else first? As you asked, is the AC on? -- "j" ganz @@ www.sailnow.com |

The solar controller is connected to the house battery, but I connect both engine and house together all the time. No A/C. Engine starts fine when when all connected if panels aren't charging, everything else works fine. Two controllers, solar and balmar but the balmar doesn't kick in for 45 seconds after the engine is started. Remember it works find unless the voltage is driven to 14v. Tom |

Why do you have the solar charging both house and start batteries??
If there is nothing other than the starter drawing of that battery, why charge it. You're most likely going to kill it. I have solar and wind. They go only to the house bank. The start battery only runs the windlass and starter. I gets charged by the engine (running) and dockside. |

The engine and house are the same size (100ah), I only have 2 and just use them together, it's not a separate smaller starter battery. |

The engine and house are the same size (100ah), I only have 2 and just use them together, it's not a separate smaller starter battery. So you actually have one bank with two batteries. I had an opposite problem - low voltage issues that affected starting over the years. The final diagnostic that clarified everything for me was the old "screwdriver across the starter terminals" trick. My problem was that the "neutral lockout" wires that went back to the gear shift before feeding the solenoid were too small so the solenoid didn't always get enough voltage to trip. One thing is that I thought I heard to solenoid tripping but it was something else clicking - this became clear when the screwdriver test showed that the solenoid was perfectly willing to fire when it had sufficient voltage. WARNING: the "screwdriver test" send a lot of current through the tip - it will likely be charred and there will be many sparks. This problem is more perplexing because a high voltage generally cures more problems than it creates. I can only guess that one of the charge devices is actually a drain in some situations. |

I actually have 2 solenoids, the starter solenoid of course, then another to trip the starter one (yanmar). |

more problems than it creates. I can only guess that one of the charge devices is actually a drain in some situations. Agreed, that's why I think it has to be something electronic (built in safety override thingy), I haven't tried to put a meter on it yet, just thought maybe somebody knew what it could be off the top of your head. Note, the newer yanmars come with more electronics; engine panel/tach/ hr meter. I don't like it. Should electronics that are design for 12v be able to function at 14v? I would think so. |

Note, the newer yanmars come with more electronics; engine panel/tach/ hr meter. I don't like it. I didn't find anything suspicious in my Yanmar panel, for 2GM20FC's with saildrive, other than overly long, thin wires for the neutral lockout. I'm a bit surprised it comes with the second solenoid. I was about to add that to mine when I discovered the wire issue. This does lead to an easy test - just short the "low current" solenoid output and see of the starter solenoid trips. Should electronics that are design for 12v be able to function at 14v? I would think so. Certainly anything that runs with an alternator active has to handle 15 Volts, or even a bit more. However, if your devices are unregulated that could put out a lot more - 18 Volts or more. Still, I don't wee where the problem might be so I'll be very interested in hearing abotu the eventual solution. |

The solar controller is a ProStar PS-15, its connected to the inputs to the inverter which is connected to the battery bank via very large cables. The prostar is right next to the inverter. The inverter is a Freedom 20 and it not on when the problem occurs and the alternator controller is a ARS-4 (balmar) which has a 45 second delay before it kicks in. The prostar has PWM regulation, and is connected to 4 panels with 186 total wattage. It's in PWM mode when the problem occurs. Tom |

Looks like the solar controller sees to much of a current draw and shuts
down. This shutting down affects the whole system. http://support.morningstarcorp.com/ Put the solar on the house battery only, not the starter battery. Isolate the house from the starter battery. |

That's the only explanation that makes sense to me: If the engine has electronic controls they may be interpreting an over voltage condition as an error, or perhaps an over voltage causes the controls to malfunction in some way. |

No, that's not it. The controller doesn't care about current draw. It works off voltage sensing. It only cares if the voltage becomes too high or too low. Either way it will regulate voltage so the battery is not damaged by overcharge or undercharge. But it also has a regulated circuit for things like refrigerators, etc. so they don't run all night and cause the battery to discharge so much that it becomes damaged. This guy obviously has not read the installation instructions and has the regulated circuit connected to the controller which regulated circuit is attempting to provide current for the starter motor. He's got the controller wired incorrectly just like I told him a couple days age. But, did he listen? So what's the use of trying to educate someone with eyes that will not see? Wilbur Hubbard |

Put the solar on the house battery only, not the starter battery. Isolate the house from the starter battery. Clearly this is a more sophisticated setup but the OP says that the two bats are switched together, so he actually has only bank. Also, he implies that flipping a switch on the control allows it to start, so the real issue here what could cause the problem, not how to work around it. Since I use solar panels and controllers, and have considered upgrading to the one mentioned, I'm quite curious about this. BTW, The controller I use in the summer (I forget the name, but it has a nice volt/amp display) flakes out in the winter (below 50 degrees) so I switch back to an older basic Morningstar Sunsaver to keep the batteries charged while the shrinkwrap is on. |

Wilbur Hubbard It's not wired incorrectly, and there is no circuits wired to the controller so its strictly a voltage problem or something about the PWM that is screwing up the starter circuitry. You have no idea what you are talking about...but I should have expected that on a USENET group. |
