[QUOTE="ionbeam, post: 1322776, member: 277"] The R/R wires go to the starter relay where they join the heavy battery cables on studs with nuts (so to speak [IMG]https://www.fjrforum.com/forum//public/style_emoticons/default/wink.png[/IMG] ). The top engine casting is uniform to the starter housing. Other parts of the motor and frame can be isolated by gaskets, relying on bolts for electrical continuity. Steel fasteners into aluminum, especially where water spray is present can lead to galvanic action and accelerated oxidation. A fun byproduct is frozen bolts. Another unadvertised special of aluminum is that the rate of metal expansion is very different from copper. This expansion difference with heat is why we no longer see aluminum wiring in homes or house trailers. Without special pigtail connectors to interface the different metals heat expansion would loosen the connections resulting in repeating heat/loosen cycles that results in flames. [/QUOTE]
