test cables and plugs
Thanks for ATS cable tester link. I just ordered one. Was on my to do list.
I can attest that if you have a plug or wire failure, it can potentially get very expensive, i.e. must buy a new mag/EI, or worse.
Re the plugs, among all the other physical indicators, if one ohms out much higher than the rest, replace it. Can read about this elsewhere.
And ditto for the wires.
Wires/plugs can go from working to not working without notice. Readings far different from the rest about all the notice you get, if that, before a problem arises.
