Yamaha Charger Model # SCR481717 Blinking Lights

[aproteau]

Hey guys! I have a 2004 Yamaha G27EZ Cool cart. It did not come with a charger. I bought this SCR481717 charger used and I was told it didnt work having 2 lights that come on, Abnormal and Incomplete. It did do this after plugging it into the cart. I left it plugged in most of the day and when I last looked ALL the lights are flashing. Its not clicking or humming. I need this charger to work and would appreciate any and all input. Thanks a bunch! AL

Too low pack voltage on cart is my first suspicion. The 110v power source is my second suspicion (does other stuff work on that 110v outlet right now). You have a MAC charger that was Yamaha original equipment, and pretty reliable. The lights & board on that charger are activated by the 48v cart power, NOT the presence of 110v house power (something many users cant easily grasp). Does the cart drive/run right now? If you plug that charger into the cart with a dead (non running, low battery voltage) cart, the lights may flash forever. You may just need to boost the dead batteries. Too dead batteries for the automatic charger are any 48v set that is currently below about 34v (automatic charger is not sure it is hooked to the correct type batteries, so wont turn on). I hope its one of these two things, if the control board is bad, its about the same price to just buy a new DPI charger. Dont waste time with the cheap aftermarket replacement board for that charger, its junk & will reduce the life of your batteries (not sure how good the batteries are right now). When working correctly, it is a great 5-stage charger & an innovative golf cart charger design when it was new (like a DPI, but no float charge). If you are unsure, get your voltmeter out (necessary for "fixing your own stuff" on a electric cart), and post your readings from each battery here, so we can help you more effectively. If you end up needing more help diagnosing the charger internals, i will be glad to help, if you are familiar enough to deal with more technical electrical testing.

Thanks so much for the info CG. The batteries that are in the cart are low but drove the cart around the block a few times before it stopped totally. I have a new set of 48v batteries here that I am going to put in this weekend. I will plug the charger in to them and see what it does and post the out come. I bought the charger from a local shop knowing that it needed something fixed. He said he was getting the incomplete and the abnormal red lights blinking.. Im also going to try a different extension cord to the charger as well.

A friend had a problem like yours and he found a corroded battery cable that he had overlooked.

Ok, so after a bunch of swapping batteries and playing around, I went to the local battery guys and borrowed their charger to jump mine. I hooked up their Stanley all in one charger and then plugged this one into the port. It cycled and and started. I left them both connected for about 1/2 an hour and then disconnected the Stanley. Yamaha charger stayed running and after about 4 hours stopped and the 2 red lights stayed on. Incomplete and Abnormal. I drove the cart for about an hours time over the past few days and I just put the charger back on it. I cycled and turned on for about 1 min and turned off. It did this about 5 times and then stayed on. Its currently connected and is turning on and off.... Im at whits end....

If all connections are good for charge wires & plug & socket, starting to sound like a bad control board in charger. Bad news is OEM control board is as much a new DPI charger, and the aftermarket replacement boards are crap...

I agree with gctech. Tried an aftermarket board once..and only once! You can buy a great DPI charger from site sponsor www.cartsunlimited.com or Amazon.com Just make shure you order it with a MAC dc cord end.

DPI calls it the "nabson" plug (nabson originally made it for MAC). And the labels on the boxes i get from DPI also say Nabson 48v on the id sticker. If you get it from ScottyB (www.cartsunlimited.net), and ask for a yamaha 48v plug, you should get what you need.
