I want to charge a kids ride on car using a battery maintainer. The battery maintainer can be left on as it shuts itself off when battery charged.
However the charger I have tried needs to "see the battery" but there is a diode "hiding" the battery state soldered on the postive connection of the socket. To prevent reverse power from the battery, it seems.
The battery is 6V 12 AH.
Can I solder a 10Mohm resistor in parallel with the diode so that the charger can see the voltage, with next to no reverse current?

The voltage (the difference of voltage) between 2 points is the same whatever the path you use to join the two points (because it is a "potential"). So, whatever you use in parallel to the diode would be at the same difference of voltage than the diode is.
