I suggest purchasing a factory service manual if you plan to do your own repairs. I will have the information you are looking for and complete schematics as well. It will pay for itself on the first repair

I have a 1990 flt tour glide classic and its not charging correctly, the gauge is under 12 volts unless you rev the engine and the speedo reads too slow and when you stop it gradually goes to 10mph, its...

Let's start by taking the battery out and taking it to an automotive part store. Ask them to load test the battery for you. They'll usually do this for no charge. If the battery test good, put it back in the bike and make sure it's charged up fully.

Now, connect a DVOM (digital volt ohm meter) to the battery. Red meter lead to positive, black meter lead to negative. Put the meter function knob on DC Volts, 20 volt or greater range. Start the engine and bring it to a high idle. You should be reading 14.5-14.8 volts across the battery. If not, check the output of your alternator.

Unplug the regulator down at the cases just to the left side of your oil filter. Look down into the connector and you'll see two pins. Put your meter's function knob in AC Volts, 50 volt range. Start the engine and bring it to a high idle. Touch one lead of your meter (either lead) to one pin and the other lead to the other pin. You should be reading thirty volts or more.

If not, you probably need to replace the stator in your alternator, If you read 30 volts or more, replace your regulator.

Now, as to whether or not this will correct your speedo problem, I have absolutely no idea.

Good Luck

Charging or electrical

First, charge your battery to full charge. then, using a digital volt ohm meter connect the red meter lead to the positive post and the black meter lead to the negative post, put the meter in the DC voltage, 20 volt or greater range. Start the engine and bring it to a high idle. You should read 14.5- 14.8 volts. If not, your charging system is not working.

Next we check you alternator. At the front of the engine case, find the connector where the voltage regulator connects to the alternator and unplug the connector. Look down into the connector on the case and you should see to metal connectors. When we get ready, we're going to insert one meter lead into each metal connector. It makes no difference which lead goes to which connector. Put your meter in AC voltage, 50 volts or greater range. Very important, make sure the meter is in AC voltage range. Now, start the bike and bring it to high idle. Insert the meter leads, one into each connector. Make sure you do not touch the engine cases. You should read 30 volts or greater. If so, you alternator stator is fine but your regulator is probably bad. If not, your alternator stator is probably bad. Once you determine where your problem is, repost and we'll tell you how to repair it you wish to do the job yourself.

Good Luck

Got a 2006 super glide, the sun of gun without warning will give a little backfire and the whole electrical system goes dead, Note: with key off the needle on the speedo will continuously pulse; turn key...

first thing i think i would look at would be the wiring connections for the battery. CHECK AT BATTERY AND THE OPPOSITE ENDS OF EACH CABLE. if these are good, maybe check your charging system. sounds like it could possibly be failing. start bike and allow warmup. disconnect battery ground cable and see if it still runs. if it cuts off immediately, your charging system has failed and you'll need to determine the cause and correction.

01 heritage. Engine light comes on, odometer goes blank, speedo freezes or goes to zero, bike still runs. Loose connection? Short?

yes thats a good place to start-always check wiring 1st-sometimes things that appear normal can be corroded but i think your alternator battery or regulator is failing-test it dew u have a manual!!

Speedometer/odometer not working, can I get troubleshooting info?

you mean all lights work but speed needle don't move, its a cable problem, maybe broken or come loose from speedo. remove 3 hex screws from chrome trim on gas tank and see if it has come unscrewed, if not undo it and spin front wheel and see if the end of cable turns, it should unless its broken.

Check engine light acting up

The first thing I would check is the voltage output from the charging system. If the regulator isn’t regulating, the voltage will keep climbing as the engine speed increases. The electronics in the speedometer don’t work well at these high voltages. This would also explain the bright marker lamps. You should be able to see this with a simple voltmeter across the battery terminals.
