    excessive corrosion?

    If you swapped leads it would be + 320mV ;) It looks like you found your problem. Now all you have to do is find where the 320 mV is coming from. I suspect something is improperly grounded. Anything wired directly to the motor? Why is that? The idea of the exercise to eliminate stray...

    excessive corrosion?

    That you know of at the moment. Where does that bonding wire shown in the picture terminate? First, check for continuity between all three of anodes to make sure they’re functioning as one to dissipate any current presented. Ideally, you would want to run the following tests while the...

    Ritchie compass model 15

    What is wrong with it? My Explorer series leaked all the fluid out over the winter several years back. Shopped around and found a repair kit on the website below but decided to investigate my problem prior to ordering the kit. Turned out to be just the orings. Saved some money and ordered the...

    Automotive Ground Straps

    Ground loops probably account for 90% of all “noise” related problems reported in autos, boats and RV are a potential cause. If one component on the loop is noisy and the return current flows through shared ground connectors, this noisy component is then the source for an introduction of noise...

    Battery discharge. ...normal?

    What you’re missing is that a 12V flooded, lead acid battery is technically “dead” at 12.0 volts. At 10.5 V your down to 1.75V per cell and at risk of permanently damaging the battery. Some good information here on Depth of Discharge and battery longevity...

    Battery discharge. ...normal?

    800 CCA is a meaningless measure of power for this discussion. The number your concerned about is the batteries Reserve Capacity. RC is the time in minutes that the battery can sustain a 25 amp load and remain above 10.5V. 140 Reserve Capacity = 140 Min. - (140/60)*25 = 2.333*25 = ~58Ah...

    Battery discharge. ...normal?

    Something isn't right. 3AH x 24 hours x 14 days = 1,008AH capacity? 3AH (125mA) per day x 14 days = 42AH capacity? To put this into perspective.......my Grp. 27 Deep Cycle are 110 AH What is the AH or RC rating of the battery in question? Bear in mind the AH and RC ratings are based on...

    Dual Battery ... Wiring fail or I just don't understand?

    Both battery ground cables get tied together on battery #1 I'm going to take a wild guess that you unhooked the ground cable (from Battery #2) from the system when you disconnected battery #1. No ground, no power

    Because Best Engineering practice dictates one ground cable to prevent ground loops, especially when computerized system are involved https://www.controleng.com/articles/ground-loops-and-their-cures/
