Question about 2002 Harley Davidson FXDWG Dyna Wide Glide

1 Answer

2002 Harley-Davidson FXDWG Dyna Wide Glide. The engine LIGHT is ON.

Went out to start the bike last week and the battery was DEAD. it was three years old so I replaced it with a lithium battery. Went for short ride and after about 5 miles the engine light came on. When I stoped at a light it went off. Took off and it came back on. When I slowed down or made a turn it went off until I increased speed. What could cause this?

Question edited for FULL maker and model name.
Question moved to correct category.

When you disconnected the battery, all the information stored in the ECU was lost. It has to learn everything again. The fault light was transient, it came on and went off. You only need to worry if it stays on.

2002 Harley Davidson FXDWG Dyna Wide Glide no electrical power @

Hi, Tracy, this is the sort of electrical problem that is probably mechanical. In other words, a complete failure like this suggests there is a break in the wiring or a blown fuse. If nothing on the bike is working, but the battery is fully charged, there are not many parts of the bike that can cause that lack of power. I can only recommend starting at the battery and working your way along with the wiring, checking every connection, including the ignition switch. There is probably a broken connection or failed electrical part that should be obvious when you come across it.

How much oil in a 2002 wide glide

Unless they've changed something, most Wide Glides hold three quarts of oil. Always check the oil level with the dipstick. There are two marks on the stick. The lower mark is "Full Cold" the upper mark is "Full Hot". Check the oil with the bike on the side stand.

Good Luck
Steve

2002 Dyna wide glide. Will not IDLE

not running for a year! You have a varnish buildup in the low end circuit of the carb. You will need to remove the carb and do a full teardown of the carb to properly rectify this problem. SOMETIMES we are able to free up the passages by putting SEA FOAM cleaner in the tank , fill her up with fresh fuel and ride through the tank and it will clear up. SEA FOAM can be purchased at an auto parts store and is sometimes very effective. 1/4 cup to full tank fuel.
