Bike just out of storage, battery seems fine but no electrical at all
Hello,
I'm a newbie when it comes to motorcycle repair and I was hoping someone may have seen this problem before in the hopes of a quick fix. I've had my bike in storage for the last few years plugged into a battery tender. I recently tried to take it out, but it's totally unresponsive (no lights, horn, ignition). My obvious thought was the battery, but the tender says it's charged and the fuses look ok as well. Bike is a 2009 250R. Does anyone have any ideas of something obvious I'm missing? Thanks! |

Hi Lucas & welcome to Ninjette!
You need to measure actual battery-voltage to determine state of battery. Measure again as you push START button; actual voltage-drop is sign of battery-health. And pull each and every fuse and measure its resistance with multimeter. There is no "looks OK" test for fuse, only objective and quantifiable test is number of ohms resistance between legs as measured by multimeter. https://learn.sparkfun.com/tutorials...multimeter/all If I had penny for every time I've heard fuse "looks OK" and it actually didn't conduct electricity... Well, I know it has cost me thou$and$ of dollar$... |

Right, and measure it with at least some load on it. I know the headlight won't come on until the engine is running, but make a brake light try to come on while you're measuring the voltage at the battery terminals. I bet you find something close to zero.

Agree.
Unless a critter chewed through wiring, most likely cause is a dead battery/ blown fuse that appears normal. Edit:: on second thought ( if not mentioned before) check that the screws to hold terminals/connections are fully screwed down, and not barely in contact with the post. Sometimes they can loosen up. If it's been sitting several years, I would replace the battery/change all fuses regardless. Last futzed with by GAU-8; September 23rd, 2019 at 07:46 AM. |

Also measure resistance of battery cables end-to-end. Since current actually flows on surface of wires, not actually inside, any corrosion would seriously impeded flow. Cables can "look OK" on outside, but there can be serious black/green wire disease underneath. This is actually very common on bikes that's been sitting outside.

It's a good idea to check the cables, but DC flows throughout the cable. It's AC that exhibits the skin effect, causing current to concentrate near the surface of conductors. It mainly becomes a concern at radio frequencies and is prominent at UHF.

OP reported bike in storage on tender for "the last few years", I'd be compelled to question the effects of such long term "tending". For sake of knowledge....load test results? But fresh replacement in best interests of OP going forward.

Yes, tenders keeping battery fully-charged at "float maintenance" 13.6-13.8v full-time is way, way too much for long-term storage. That's stage-7 on sophisticated chargers such as Ctek 8-step charger (provided by BMW & Porsche as OEM charger).
After battery has reached stage-7 Full-Charge Float-Maintenance, it's allowed to relax at stage-8 Long-Term Storage. This turns OFF charger and lets battery drain to 95% (weeks). At which time, it's pulsed-charged back up to only 99% and charger turns off again to let battery self-discharge back to 95%. This allows battery to last years under Long-Term Storage and not get fried by 100% Float-Maintenance mode like tenders do. |
