When I turn the radio on with the compressor ground connected the radio breaker trips. The breakers in Gamma are an aviation style breaker, they look like what you have in you house breaker panel. If I remove the radio from the hull, I can turn it on just fine with the compressor ground connected. I am wondering if my radio is shorting out so there is pos current in the cabinet and the compressor is providing a ground for it to short out.</div><div id="yui_3_16_0_ym19_1_1465473702416_4810" dir="ltr">I will instal the transducer and do some more testing, I can put the surface radio transducer on top of the sub transducer and test to be sure the radio is actually working still. </div><div id="yui_3_16_0_ym19_1_1465473702416_4810" dir="ltr">Hmm now I am wondering if I have the power reversed on the compressor and I am turning the sub into a positive ground, the compressor should still work with polarity reversed. </div><div id="yui_3_16_0_ym19_1_1465473702416_4810" dir="ltr">Thanks' guys.</div><div id="yui_3_16_0_ym19_1_1465473702416_4810" dir="ltr">Hank</div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font size="2" face="Arial"> On Wednesday, June 8, 2016 8:26 PM, Sean T.

There should be no continuity from either battery terminal. If there is, the DC power supply common is tied down to chassis at one of the devices. Check the radio antenna as a possible culprit.</div>
<div dir="ltr">Next, check the potential of each power supply connection, not only between + and - at the device, but with respect to each other as well. (You mention tapping 24 V off a 36 V battery - any chance you're between +24 and "0" on one device and +36 and +12 on the other?)</div>
