Re: Wiring GPS question
Your problem may be larger than it first appears. You probably aren't having a power shut off, what you are likely having is a severe voltage drop. Its not that you loose all power, its just that the power drops down to below something like 11.6 volts (I think that is the Garmin threshold) and the machine shuts itself off. <br /><br />The real problem here probably is that the power feed up to your ignition switch is not large enough to support all of the stuff that you now have it feeding. What you really need to do is run a new, and heavier, power cable from your battery switch up to the console, let it feed either a fuse panel or a breaker panel, then hook all of your electronics to it - after you take the in-line fuses out of the lines and see how far you can throw them.<br /><br />So, there's what I think your problem is and there is your solution. A lot of guys will simply put up with the voltage drop and get in the habit of turnin on the electronics after the engine is running. That will work for a while, but as soon as the terminals on that already over stress wire start to corrode it will get all the worse. You might also want to be taking a look at your actual battery cables, not only from the engine to the battery switch but also from the battery to the battery switch. Corrosion there will also result in a substantial voltage drop but in the end it just about always an undersized power supply wire that causes what you are seeing.<br /><br />Thom<br /><br />Oh, it could be just something as a old weak battery, but I assumed you checked that before posting.
