My 2016 yamaha EFI cart is flashing code 55. Anyone know what this code is. Google has been no help so far

[KennyP]

There is no code 55

[Dave951]

It has 5 slow flashes followed by 5 fast flashes

[Dave951]

I checked the battery voltage and charging and did a battery load test and voltage drop to the stater/generator and the battery will only recover to 11.05 volts. Looks like it's getting a new battery

One known “worst case” problem is the wiring harness. If that turns out to be your problem and you decide to fix it, be certain to get part number: JC0-H2590-40-00. Do not get part number: JC0-H2590-20-00.

If you are getting only 11.5 volts on the battery, yes replace the battery. NOTE: these are regular automotive batteries, so you can take out your old battery (NOTE the location of the battery terminals), and go to any automotive parts store and MATCH the battery, I think these are 24F (BUT CHECK), replace the battery and see if the code clears. We got a low voltage code (46 I think) when the battery was failing.

I replaced the failed battery on my cart with a deep cycle marine battery from Sam's club. I think it cost $85. 15 months, no issues.

Also, I found that the wiring harness was inadequate for the load, so I put the headlights on a separate dedicated circuit, 14 guage house wiring with a ten amp fuse, and this solved all the electrical issues.

In Florida heat batteries tend to lose water. Check the electrolyte level every couple of months.

Glad you mentioned battery water level. I haven’t check mine for while and water level was below the plates. So I add some distilled water.

I my case my car battery will fit in my cart. I only have one car now so I replace battery every 5 years here in hot Florida put new battery in my car and turn I the old cart battery and put the one from my car into cart.

Change the battery...Id bet your issue goes away.
Those of you saying to add water to your battery? Most are sealed now a days, but I see many who buy the lower cost batteries, so these must be non sealed batteries.

[ronda]

Yeah, I was thinking the same thing.....do they even sell non sealed batteries?
I thought all batteries are now "Maintenace free".
I don't think the OP has an electric cart? Those batteries may need water added???

They do sell non sealed batteries today; not every battery is maintenance free. Besides, the OP is asking about the battery he has had in his cart for awhile, not a new battery.

The OP does not have an electric cart, he has a Yamaha EFI.

In the case of electric carts, older ones use lead acid batteries that may not be sealed. Newer carts use Lithium Ion batteries that do not use water and need no maintenance.
