  • did i see toeboards?

  • @cougar1972xr7  Yea you did..

  • Why that type of cutoff switch is bad is easy to understand when you realize that the motion of electricity is expressed along the outside of a given strand of wire. High current high load applications use many fine strands, and is why a thick welding cable, if cut open, will have very fine strands of wire. With that type of switch, you take a multi-strand high load battery cable and turn it into a single strand wire (the two plates held together in the on position) That creates a choke point.

  • @MrComaToes Makes sense to me. All I know is that I got two of 'em that you can have if'n ya want 'em. haha

see all

  • floor boards,,,,must be a hi end shop,

  • @hoppes9 Which, is really all I was trying to say in the first place! ...but in any case, it's neither a well made or properly designed cut-off switch.

  • thst engine won't have the power it should have. it has no back pressure.

  • @MrComaToes Right - the "choke point" there is due to corrosion of the open contacts in the switch.

  • You can't have too many "milk crates" when yer building a Rod!

  • @hoppes9 I'm not an electrical engineer, I'll leave that to the experts. As a practical matter, every connection a wire makes is a potential "choke point". I have had many opportunities to observe the behavior of this exact type of cut-off switch over time. What invariably occurs is the resistance (already higher than a connection straight to the battery) thru the unprotected connection plates, rises to the point it becomes a choke point that can kill batteries starters and alternators.

  • @doberfag Try it again and see if I fixed it. I'm trying to figure it out .

  • @hoppes9 Skin effect- Exactly what I was going to post in response, but ya beat me to it !
