Reasons battery drains overnight
Funny, I've been disconnecting the battery after every time I finished messing with the ignition installation, and lastnight seeing that everything was working well I left the battery connected, and the day i go to start it up the battery ends up dead lol.
What's the reasons a battery will drain with the bike completely off?Ian

Blown SH775? Colour me skeptical; at least from what you've written...but I guess you did check voltages etc.#1: 1979 GS 550 EC "Red" – Very first Bike / Overhaul thread New here? ☛ Read the Top 10 Newbie mistakes thread

Nevermind on the order, bike is just frustrating and I went to buy a part thinking that's what it was but more than likely isnt.
I dont know what the heck is going on.
Stator is bad but I'm just trying to get the bike running correctly before I replace, I thought maybe the regulator was sending inconsistent voltage throughout bike but its obviously separate from the ignition system. Gonna need a day or two off.Ian

“Gonna need a day or two off.”
good plan , take a break and head to beach.
A fully charged battery will let you run for about 45 minutes...unless you do a lot of starting.....so disconnect charging system and figure out idle issues .
I doubt you can smoke a sh-775 even with bad stator.1981 gs650L

Hopefully lope goes away when carbs are sorted.
Gonna take a slow-mo video of spark plugs to ensure they are firing correctly.Ian

If you ever need to look for a battery drain, use a multi meter and set it to amps. Normally you have to switch the positive lead on the meter to another location on the meter. You use this position only for meaduring amps, and most meters wont tolerate many amps, 10A is the normal max I see for small meters. Unhook either battery cable and place the meter in line between the battery cable and the battery. Any power being used will show up on the meter expressed in amps. You can unplug fuses, and wires to start tracking the circuit that is causing the drain. So disconnect either battery terminal, put one volt meter lead on the battery post, and the other volt meter lead on the battery cable you disconnected. Don't turn on the ignition or try to operate the starter with the volt meter hooked up like this of the meter will likely get overloaded. Remember to switch the red probe to the amps socket on the meter. Don't forget to switch it back after you are finished, If you don't switch the red wire back to normal and you try to measure volts the meter will cause a direct short and blow the internal fuse in the meter. It is also worth while disconnecting your battery and see if it self drains overnight. Certain battery problems can cause a battery to self discharge.Last edited by metalfab; 04-14-2021, 01:55 AM.1981 GS1100E
