Does anyone have an original Late 1966 to 69 Shovel with the automatic circuit breaker p/n 74586-65 (not the timer) ? Where is it located? Ther parts manual shows one 8-32 screw and nut. Was it attached to the battery tray or?? This was also available with the 4" wire leads attached under p/n 74585-65 for retro-fitting to 65 and early 66's. One wire lead went to the regulator Bat terminal and the other end went to the battery pos. Anybody have a copy of the instructions that were included with the kit??
