No, I am no expert either.
Yes, I am also glad jopete found his bad connection.diamondback0320 wrote: jopete I understood what your thread was about.. Was just reading a response of somebody talking bout taking off positive cable when in around the motor I guess believing that that has any affect on the mags..which does not,I think lmao!
Yes, that is not effective in making an aircraft motor safeGary S wrote: I don't use battery switches never found a need fore them. If I am working around prop I remove the positive battery cable.
Yes, this thread has taken an unexpected turn.
So in the interest of learning and safety, I will try again:
The Positive cable off disengages the starter and othe electrical stuff.jopete wrote:yep, when i work around the prop, perko switch is off, positive wires pulled off the battery, and all switches off on panel.
If the perco is on the positive and off, disconnecting the positive isn't necessary.
My question is about if the the perco is on the negative. Does that disable the mags?
How does the electricity flow through the plugs into the motor without a place to go?CactusJack wrote:
Yeah, that is why people need to take off spark plug wires if planning to turn the crank of a motor on the bench... it might fire if it has mags and plug wires connected....
Yes, they still make electricity. Yes, it has the ability to go through the plug wires and to the plugs. Yes it has the ability to go through the plugs and into the block. But if there is no ground from the block, will the plug still fire? I thought the plugs needed the ground to the battery to complete the circuit. If the mags create electricity that can spark through the plugs with no ground or completion of the circuit to the battery, do they complete the circuit back into themselves? What completes the circuit? And if the electricity is flowing from the mags to the plugs into the block and back into the mags to complete the circuit, why can't we ground lights, or the starter, or anything else to the block without a good ground to complete the circuit?
