Yeah so, what is the use of a multi meter. I have 2 batteries the same, had to buy a 2nd, as the first one boiled due to a faulty reg/rec so, the multi reads 12.5-13V on both, but they're operating the bike completely different After arguing with auto elecs about why my battery is showing 12.5 V and still not operating correctly("Well, maybe your stato, reg/rec wiring loom is faulty, have you checked your tyres"!!), i hadda buy a new one By correctly i mean, my new battery, switch on the ign. lights work as do the indicators, hi beam lo beam etc.. switch to bad battery (same V reading) and no lights, indicators barely if no light switch on etc etc ETC ETC So the batterys both read the same, but one doesnt work How can u tell if a battery is good using a multi, can u??
