Voltage Low, Red Brake Light Flickering Options

[mzapisek]

All original 1.7. Recently noticed voltage reading low (10.5) and red light which indicates emergency brake engaged flickering. I replaced the E brake trigger switch not thinking the two issues were related which did not not solve the flickering. Also noticing a periodic hesitation when driving. Any thoughts on what might be causing these symptoms and if they are related? Thanks.

Honestly wouldn't be worried about a handbrake light,time to address low voltage in your system ,soon but not later you will have insufficient voltage to your coil and more importantly your starter won't turn over,DON"T take voltage from any where but the battery,you should have 12 + volts at rest and 13.4 to 14.4 under full charging load.
Do you have a working charge light?

+1. My GEN light used to come on and the center console voltmeter showed low voltage, but I had 13.5V at the battery with the car running. Bad grounds/bad connectors are common with our cars (I eventually removed the center console after I cleaned up all the connections.)

I have a corollary problem: my GEN light is on bright-ish at idle but dims as RPMs increase. Good voltage at the battery but of course lower voltage at lower RPM. So the GEN light is in INVERSE indicator...!

Need to break out the wiring diagram and figure out what's going on there. Good battery voltage at the fuse and the input wire, need to ring the wiring to see if there's some kind of connection problem to the alternator.
