Hook it up and use dielectric grease on all connections. Without a space for an electrolyte (salt water), the different metals will remain corrosion free. Once connected and tested, a light coat of battery spray coating will prevent surface corrosion. Copper buss bars, lead terminals and stainless screws have been used for many years together, don't worry.
| Last year when the display on my Zantrex XBM battery meter display died. I purchased a Paktrakr battery monitor with the optional current probe as a replacement. But, thanks to a tip from Mathew Geier here on the Electric Boats list I was able to get a replacement part and fix the XBM: http://biankablog. blogspot. com/2009/ 12/going- electric- repairing- zantrex-xbm. html I still hooked up the Paktrakr which works great for measuring the individual battery voltages but, I never did hook up the current probe.The Paktrakr current probe requires I use a copper bus bar attached to the most negative battery negative terminal. The Paktrakr current probe slips over this copper bus bar and measures the induced current. I have been debating about whether or not I should install the current probe for the following reasons: 1) It adds another connection point in the system and a possible failure point. 2) I am concerned about corrosion issues. The bus bar which is copper will be connected to the battery terminal (lead) with a stainless steel bolt. My boat lives in a saltwater environment and worry that galvanic corrosion might be a problem. So I am turning to those on the list for advice to this dilemma. It would be nice to have a backup current meter via the Paktrakr. Am I worrying to much about the corrosion/connectio n issues? I welcome comments on this issue. Capt.
