'92 Heritage won't crank

most anytime ya get a goooo comming from an electrical item, it is not a good sign. have you done an onboard diagnostics????

Not being there is always hard to help out but how is the battery as you stated it won't crank does that mean cranks slow or it turns over normally. If OK a weak spark will not be enough usually to fire it over. Did you connect all the wiring correctly? Any kind of bad connections or loose grounds won't help.The voltage should read around 12.5 volts (higher is OK) If the voltage is less than this it may indicate a poor battery and can cause a weak spark.

Confirm that the electrolyte level in each cell of the battery is good. Add distilled water only to cell's with a low level. (Obviously you cannot add water to a maintenance free battery) Charge the battery overnight with a slow charger only. Motorcycle batteries cannot handle a fast charge. Make sure the charger only charges at a rate of 2 amps or less.

Install the battery and try and start her again. If she still won't go buy a new battery and your problem will likely be fixed. If she starts and runs like a charm, then you have to find out why the battery went dead. You need to check the charging system.

With the engine running, place the multimeter leads on the battery. Rev the engine a little. The system voltage should rise with engine RPM. A voltage of around 13.5 to about 14.5 should be displayed. If the voltage stays constant and/or is slowly decreasing, or if the voltage rises above 14.7 volts the charging system is not functioning.You have to check two things. The Stator and the Regulator. The stator creates an AC voltage. The regulator changes the AC to DC voltage and also maintains that voltage at the proper level.

The Stator can be checked with the Ohms function on your meter. Locate and remove the plug for the stator on the front of the engine block. You will see two or three pins inside.

Set the meter for low Ohms, and measure the continuity between these pins. 5 Ohms or less is what you are looking for here. Set the meter to the highest setting. With 1 lead attached to a metal part of bike check for continuity to each pin. You meter should read infinite, or no continuity. If these tests check out then your stator is fine. If there is a fault in any of these tests, then see your dealer

The regulator is the easiest of all to check. The regulator is made of solid state electronics and can't be opened. Replace the regulator if everything else on the charging system checks out or if there is an overcharging situation.

On most Harley's you will not know if the charging system is beginning to fail. The evidence shows up when you have dim lights or she just won't start. There are aftermarket accessories that you can install on your bike that will tell you the current state of the charging system. Hope this helps.

I've found that generally if you let the smoke or goo out of an electrical device it tends not to work, these things for some reason run on smoke and goo, I don't know how they do it.

If you have fuel, compression and spark it should run, was it running before you put on the new plugs and wires?

What year and model bike, honda? harley, ducati, Crosley?

92 heritage

guess I'm a bit slow I read the msg and missed the title duh

When you say it won't crank do you mean it won't turn over
or turns over very slow?

If so check battery, have a load test done on it at an auto parts
store it might charge but not hold one. If you replace use a
HD battery about the best out there.

If it turns over fine, then check all the wires and connections

A bad ignition module will do this as well, you might be getting a weak spark,


I'd check the battery, ground cable and connections before anything else.

My brother's 89 evo had all power but would not crank check it all out it had A bad stater, My bro -law's 00 TC had the same thing go out on his we pushed started it & ran like always just would not crank by the button or jumping it

Well that would do it.

the Ultima will be a good motor.

is the cam broke or pieces missing where the brg rides??? i have seen/heard of this happening.....
