Being the curious sole I am, I decided to take apart the “BIG Battery Switch” that I had in my trunk as a safety cut off from my battery. It’s been in my Tiger for about 12-15 years without any problems, I remember once that I had to “exercise it” to get it working again, but other than that no problems. A few days ago I tried to start the engine and all I heard was a “click” then nothing, noting that the fuel pump wasn’t working I figured that it might be that “BIG” switch so after many “exercises” there was still no voltage past the switch. After removing the switch behind the right fuel tank (what a pain) and cutting it in half on my lathe, I discover what you see in the photo. The actual contacts in that “BIG SWITCH” are no bigger than the head of a pin!!!<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif"'> This switch is the “standard” 125amp switch you see everywhere in auto shops. How 125amps @12V can pass through that tiny spot on the contacts is very surprising to me! My guess it’s can’t!<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif"'>That rectangle blade is what rotates 90 degrees to make contact with the two tops of the bolts inside the switch.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif"'>I have replaced the switch with one that has a higher rating (300amps continuous, and 500amps momentary). Looks a lot like Summit’s #830054.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif"'>Let’s just say you were trying to start the engine and it just won’t start and you keep cranking on it , just how hot do you think those measly small contact points would get? Next to your gas tank of course. Just saying!<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif"'>Jerry Christopherson<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif"'>9473187<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial","sans-serif"'>TAC insp. #58<o:p></o:p></span></p></div></body></html>
