Sometimes, just sometimes, I can correct my mistakes before I call the repairman or make a long distance call to San Francisco.
I plugged the power cord into the power chair over night. Yet, this morning, when I used the chair, the battery indicator showed only partial charge.
"Oh, my gawd," thought I. "I'm going to need a new $200 battery." I nursed the chair around this morning on its weak battery. At noon, I plugged the power cord into the chair again. But I noticed that the ammeter was showing NO charge.
"That's even worse. The battery may be okay but I will need a new charger. $400."
"Perhaps I just need a new power cord." I had hope. I jiggled the cord. No response.
Then one my few good ideas hit me. I checked the connection of the power cord to the wall socket. It was loose.
I re-plugged in the power cord. I checked the ammeter. The charger, at last, was working well.
I am not sure whether I saved $200 or saved $400.
Either will do.
