    You make an "open" in the circuit in question, either at the fuse of by disconnecting a wire, and then insert the test light in series.

    Yes, I realized later that is what he meant. Novel use of a test light. Thanks.

    Thanks for all the good info!
    Let us know how things turn out, so we can add to our understanding of these types of issues. Thanks

These test lights are very useful if you're looking for a hot wire ( ignition on or off ) on your car or spyder.

    you are right and if the test light lights up then start pulling fuses

    Does any one know how many milli amp should be drawn when bike is turned off?

    I think pretty much zero. Maybe DESS draws a little, but every other load should be pretty much isolated from the charging circuit, I would think. I've had my bike sitting for 2 months or more without a battery maintainer hooked up and the battery was a little down but always has enough to start the bike.

    Actually, from what I see on the wiring diagram the DESS is fed from the ignition switch. The ECM, cluster, and radio get power full time but I've no idea how much.

    Just a simple question for the electrical engineer's here:

    Putting a VOM in series with the negative terminal of the battery and the neg. cable ( set on amps of course) should give a reading. Ignition off-- VOM on Milliamps.

    Just want some input before I try it.

    Just don't turn the ignition on or hit the starter. You'll most likely fry your VOM, or at least blow its fuse!! It'll be interesting to get an idea what the current draw is.0

    I would test the circuit draw at the positive terminal, I think. Start at the highest amp range then work down from there.

    Either terminal will work equally well.

    Spread some newspapers under the Spyder so you can see where the electricity is leaking.

    I think if it's more than 3Ma you have a parasitic draw. I'm just going off the top of my head as a standard.

    I just went through my manual. 10-20 mA draw is within normal. Sorry.

    I'm not trying to start a tire pressure/ tire size/ oil brand, ect. war here but:

    Removing the negative side is a lot safer on a neg ground vehicle. If you testing with the positive side un done and touch any grounded metal with a load---- you may fry a meter set on milliamps. Always start with the highest ampere setting on the meter .

    Lew, it doesn't matter to me which side of the circuit is used for this test.

    I was thinking about that when I responded but I just wanted Pete to be aware that as far the flow of electricity goes it makes no difference which side is used.

    Hi Pete,
    Just looking out for your( and others )safety. I have an expensive VOM and I wouldn't want to fry it. When the + cable is removed first-- any touching of a conducting material will cause a direct short.

    Hope your winter is treating you well. We are getting blasted now and another storm tomorrow, Oh boy.

    Kaysville is north of Salt Lake City. About 50 miles from Oakley. We're at our winter 'retreat' in southern Utah, where we are getting the cold but at least no snow.

    I did know that. I was just thinking that ammeters are usually wired in on the positive leg of a circuit. Thanks fellas!

    With US automotive wiring methods, in general you would want to do that if your measurement of interest is a specific electrical load, if the ammeter is wired in securely or permanently. The US standard is to switch the load on the positive or power side. With Japanese vehicles, and most of the circuits in the Spyder, the controls for power to a specific load are usually on the the negative or ground side of the load. In that case you might want to put the ammeter in the ground side as it usually is specific to that load and not shared with other loads.

    I've never figured out why the Japanese like to switch the ground side and not the power side in vehicle and electronics wiring. You sure don't want to do that with house wiring and voltage!

    In the case of the OP's question, we're looking at a very temporary situation so safety is the overriding consideration.

    Which terminal you use makes no difference......except that if you make a klutz move and short something out, the negative side is MUCH less likely to cause any damage.

    And yes, you always should start with an AMPS range and work your way down.
