I have a question-Ammeter is showing negative numbers.
If you place the shunt between the master solenoid and battery, it could show either positive ( charging the battery), or negative (draining the battery). A negative value would be normal if the engine is not running. If you got a negative while the engine was running, you probably have alternator problems.
What is negative voltage?
Say there''s an electrical potential drop from 5V to 3V. A positive test charge q would add -2q to its potential energy (becoming less positive), while a negative test charge -q would accelerate in the other direction (+2V, from 3V to 5V), but also adding …

5 reasons your multimeter is reading the wrong voltage
Get yourself a new battery (AA, AAA, D-cell, 9V etc), and test the voltage. Since it is a new battery, the voltage when testing should be around the full capacity value of the battery. Again, if the multimeter …
Negative value on the DC system
due to the bmv thinking there is an additional 20w being fed to the battery from the DC system. You still don''t get it. BMV only measures the current into the battery (or out from the battery) and the battery voltage. BMV does not "think" what a DC system might be consuming or producing. BMV does not "think" what the inverter is consuming.
What is Negative Voltage?
If a battery has negative orientation, its voltage with respect to ground is more negative than ground, and it delivers positive current to the ground part of a circuit. To find out how to obtain negative voltage from a DC …

Why does the Windows battery report show that there is negative …
When you charged up the battery, this worked because it''s handled by the hardware and doesn''t require any protocol. Once the battery had some power, it answered Windows and was detected. The negative value was probably because the battery has a bit more more power storage available than 100%.

What Does a Negative Voltage Mean on a Multimeter?
Likewise, the negative terminal has a negative voltage that is relative to the positive terminal. Two batteries that are in the same series can actually split their supply where the 0V is in between two batteries so in essence the positive terminal takes from the + on a battery whilst taking the – on the other battery negative terminal.
