sealant may be used successfully for this application other sealants such as rtv silicon rubber sealant may also be used referring now to fig4 an exploded second embodiment electrolysis unit 400 includes a case lower portion 401 a case lid 402 and two groups of seven evenly spaced parallel laminar plates arranged in two spaced apart groups the first group includes laminar plates 403 a 403 g the second group includes laminar plates 403 h 403 n 403 generally it will be noted that laminar plates 403 g and 403 h each have an electrical connector tab 404 a and 404 b respectively which extend from an upper central portion thereof each of the two connector tabs 404 a and 404 b has an aperture 405 for receiving a threaded fastener that will secure an electrical cable to the connector tab laminar plates 403 g and 403 h will receive a connection to a nominal voltage of 12 vdc through connector tabs 404 a and 404 b it will be noted that laminar plates 403 a and 403 n are taller than the other laminar plates each of these two plates will also function as part of the lower case portion 401 and will be sealed around their edges with waterproof sealant laminar plates 403 a and 403 n will also be connected to chassis ground through conductors.
