You can test the Capacitor while the battery is charging.
Remove the console and remove the 2 wires that are connected to the Capacitor.
Next, use a short screwdriver and touch both posts at the same time, you will see a fairly strong blue spark 9f the Capacitor is good.
No spark means it's bad.
Once the battery is fully charged, we can start up again.
One thing I have found, when it does the PMT and it quits moving, when you turn the key off and back on it rarely fixes it and usually does a PMT again, but if i just unplug the wiring harness on the right side of the control card and plug it back in it will get it back going again for a period of time before it drops out again. I thought maybe it was a connection there but everything there seems tight and a good connection by my readings.
Did the charger turn on and stay on ?
The battery shows about half charged so I will put it on the charger now and will make sure water levels are correct after fully charged.
I do have a new capacitor I could try.
Pull out the battery and check water levels for each cell.
Is the battery fully charged ? Test battery volts.
You might have a weak capacitor or a weak #1 rectifier.
