TYM T264 HST Battery bleed

[RFoutthere]

I’ve got a bleeding circuit that takes my battery down. Took connections off alt. And disconnected virtually everything including all relays flasher etc. Still have power to red wire with blue stripe going to instrument panel. Red with blue stripe throughout seem to be powered so that may be normal. I’m leaning towards problem with instrument panel its self. Any thoughts or experiences with this?
Thanks for any input.

How are you measuring if a wire has power?

The typical way to troubleshoot a battery drain is to disconnect the negative battery cable. Then measure amperage with your multimeter in series from the cable to the terminal. You want to see the amps drop to less than 1 amp after 10 minutes. If it’s higher than that start pulling fuses until the Amps drop.

Thanks for the input. My meter doesn’t measure amps. I’ve been using volts on the meter. Pulled all fuses and still had voltage. Disconnected all main wiring loom plugs and still had voltage.
I located the diodes in the loom and they measured good. I also checked for leaks across terminals on all relays. I may make sure the battery is charged up and pull the diodes just in case they’re bleeding and I didn’t catch it. Lots of dirt. Going to get electronic component cleaner and spray all the plugs out.
Thanks Rtintwo
I’ll post once I locate the gremlin.

Ok here’s the thing, voltage can roughly equate to pressure and amperage to flow. As you measure volts you are seeing pressure in the wires but pressure does not drain the battery. Amperage with its flow is what drains the battery. The battery is a kinda like lake with a pipe out the bottom of it. You close a valve on the pipe and there will be pressure in the pipe but no flow. You open the valve and now there is flow and the lake drains out.

I recommend you buy a meter that has amperage on it, you really need the right tool to do the job. Until then you will continue to be frustrated with chasing this drain. Harbor freight has some meters that will do the job at a good price.

Note: for the “Aktualy” crowd, yes I know the fluid analogy has faults but I’m just trying to get the idea across.

Thanks. I’ll get a meter that will let me check the amps. I get the volume and flow analogy. I guess I just got fixed on voltage. Rookie mistake.

You can also measure voltage drop through the fuses. You measure voltage to ground before the fuse, and on the output side of the fuse to ground. If there is voltage drop through the fuse, there is current flow through the fuse.
