There's JLD404 meter in my car, I'm going to rewire it so that with ignition switched off (during charging for example) it measures voltage at the battery but when key is turned to "ign" or "start" a relay switches measuring points to controller's DC bus. This way I could check precharging at any time without extra equipment, just keep my eye on voltmeter during "cranking" (see above post).
