OK, so the battery drain issue.
One old way, with the clock disabled, and a Voltmeter between the battery negative strap and the battery negative post, remove fuses with constant power(red) on the feed side, to check for Voltage drop. If no luck, unplug different circuits.
That might be how electrons flow in the southern hemisfere e.g. ammeter
In northern hemisfere
A voltmeter has to be connected in parallel to the Load (e.g.resistor) to measure potential difference across 2 points
To test for a parasitic drain, you need to insert a resistor shunt into the ground cable and measure any voltage drop across it. Here's the process:
1. Purchase two 2Ω 1% 1Watt precision resistors from a reputable online electronics house like
Digikey or
Mouser. Connect them in parallel.
2. Remove all fuses and make sure the ignition is off
3. insert the resistor pair between the ground wire from the negative terminal of the battery and the grounding point on the transmission.
4. Attach a voltmeter across the resistor pair and set the scale to 1V, if available. The voltage you read will be equivalent to the parasitic current. For example, a parasitic current of 1A will indicate 1V; a current of 100mA will indicate 0.1V (100 mV) and so on. E = I x R R=1Ω
5. Note the voltmeter reading with all the fuses out and the ignition off. It should be zero or near zero.
6. Insert each fuse and read the voltage. If no change in reading, then remove the fuse and insert the next one.
7. Eventually, if you have a problem, the voltmeter will indicate a non-zero reading. Now you know which circuit on the bike is the culprit. You have narrowed your search. Diagnose the circuit.
At no time, should you turn on the ignition or try to start the bike. This will blow apart the resistor shunt with the current draw.
While connecting care should be taken that negative terminal of the VOM is connected to that end of resistor which is connected towards negative of the battery.
If VOM is connected in series then due to high resistance no current will flow through circuit so no voltage drop occur... its indicates zero and if ammeter is connected in parallel due to low resistance it will act like short circuit so chances of ammeter blows its fuse.
