Have you tried monitoring the voltage across the battery with a meter while trying to start?
You can buy a digital multimeter for <$20 US at electronic stores (such as Radio Shack in the US) or even auto parts stores.
If you have a Harbor Freight tool outlet near you, they are even a lot cheaper and you will be glad to have one when situations such as yours occur.
You gave the battery voltage as '.13' VDC so you may already have a meter but I don't think you wanted to write that you have 13 hundredths of a volt, did you?
The nominal voltage of a charged battery is 12.6 volts and normally falls ~ 2 volts when the starter is running.
Fuses: the can have a break in the element that is close to invisible so use a meter to measure each one of the higher amperage fuses for continuity on the Ohms or diode scale to make sure.
Some change in the way batteries are made have made them behave strangely; I have had several batteries that will not charge even with 20+ volts across them. They draw only milliamperes and that is not charging. I suspect they build sulfates more readily than in past designs.
