Parasitic drain again.

[jeffyjeff]

I recall I had this same problem when the alarm was still in place, but what remains of its loom could be draining the battery somehow I suppose. I really didn’t want to get into stripping that out.

Latest current readings with a much better quality meter are,

10mA between negative lead and terminal. (The Yamaha R1 for comparison has 0.3mA, including immobiliser.)
still 10mA with reg/rec disconnected.
10mA with all circuit fuses removed.
10mA with fuel pump disconnected.
8mA with main 30A fuse removed.

By a process of elimination it seems likely to be the starter motor but I couldn’t see or reach the connection to try it. I’ll tackle that another day.

I also found this battery website -https://www.batteriesinaflash.com/battery-run-time-calculator?srsltid=AfmBOory8v2nZZoqrlk22Okbr-HMVQkxGDogoZp56fcX4cvN_S51BR7i which suggests my 8Ah lead acid battery with the 0.01A draw would last 571 hours or 24 days, which tallies with what I’m getting. 10mA is too much draw.

It would be the solenoid rather than the starter and it should be right by the battery, follow the thick red lead from the battery and it goes directly to it.

Bear in mind there are two sides to the solenoid, the switched/fused side which should only allow any currrent when you press the starter button and the main feed which goes to thhe starter motor and is triggered by the other side being powered. You should be able to remove the solenoid to starter motor side of the solenoid and then check current draw there.

Do not do it on the battery to solenoid side unless yoou want all kinds of mayhem if you accidentally touch the lead against anything metal, it will just short out your battery.)

Thanks. I’ve pulled the faded red plug off the top of the starter solenoid. Current between negative battery terminal and battery post is 9mA. I’m not sure that’s the test you’ve told me to do though, Nobby. Is that good enough to confirm the starter circuit is not guilty?

Really need to measure the current draw between the solenoid and the lead.

OK, both battery terminals connected. Black lead under the large, flat-topped rubber cap (ie. not the lead from the battery positive terminal) to starter solenoid disconnected and ammeter put between the two. Zero mA.

[Nobby the Bastard]

It's not the solenoid/starter then.

Disconnect solenoid and rec and pull main fuse and then test again on the battrery/ lead. Pretty sure the draw will still be there but just to be sure...

Yep, 9mA.

Personally I'd delete the alarm wiring but being sure it's not messing with the ignition is problematic.

The alternative.is just only connecting the battery before you go for a ride and disconnecting it afterwards.

Bit of an arse if using it daily, not so much if only used monthly.

Sickpup, I said disconnect the solenoid to motor side to avoid lots of sparking if the battery lead aside accidentally touched metal.

This will be an example of when you would very carefullyremove the battery side of the solenoid a d make sure it is placed in a position where it can't short the battery.

I would inspect the harness for places where someone might have tapped into an OE conductor. One obvious clue would be the presence of "scotch locks". Scotch locks work OK when new, but they do not wear well. I would keep an eye out for a connection that looks like this:

They wouldn't have been used to isolate the ignition. That would have required.cut and spliced wires.

So it has an aftermarket alarm still fitted?

Ffs....

It's an earth. it's obviously introduced to get round another problem. It's should not a cause for why the battery is being drained.

I'd look at what its atteched to though. Probably introducxed because of shit earths everwhere else.

There's an obvious connection point there. Stick your multimeter in between the two ends.
