'07 GT250R - NO POWER! Please help.
« on: August 27, 2017, 08:39:46 PM »

       Hello and good day to anyone reading. I recently just turned 17 and I have recently purchased my very first bike a 2007 Hyosung GT250R with 15,000 KM on it. It worked fine since I got it, rode it for the first couple of days then realized my battery was not charging during my rides. I took it to a mechanic shop to get it looked at, and he gave me a dirty look saying that he can't fix "offshore" bikes. He did however diagnose the problem to be with the regulator as the stator was recently replaced by the previous owner, and same goes with a new battery. So I went online that night and ordered a used *working* regulator off eBay for $50 CAD. The next morning, keep in mind I charged the battery overnight with a trickle safe battery charger, I go ahead to switch the key ignition to ON, everything powers up just fine. I continue to try and start the bike in neutral, it cranks but wont turn on. Now me being the complete inexperienced idiot I thought something horrible was wrong with my bike, so I go ahead and bring a car battery and hook it up to the bikes battery. (Keep in mind, this is a car battery that was taken off a car so it was NOT hooked up in the car). As you all know a car battery outputs a higher amounts of voltage then a bike battery when its fully charged, so I hook it up and press the start button... it cranks and cranks but doesn't turn on. Turns out all I had to do is roll the bike as sometimes the neutral light was false and the bike thinks its in gear, as soon as I did that... BOOM bike powers up like an old rig. I was so happy and didn't realize my mistake until I see my dash powering down as if its losing power somehow. I smell burning and hear some odd small sparks coming from the battery area. I freak out and immediately shut off the bike. I realized I had the car battery STILL hooked up to the bike battery and as we all know after the bike is on we should always take it off as it might damage the regulator or the stator. Which it did nothing to the regulator as it seemed like it was already busted, but I did blow the small RELAY fuse from the HANDOUK company. But actually after a bit of reasearch the RELAY that was actually on the bike was not the correct specs as the original HANDOUK RELAY provided with the bikes factory. It was some universal Automotive 12V, 40A Power Relay used for pretty much anything. But the original RELAY is the HANDOUK 14V, 35A RELAY that my bike was mysteriously missing. I took off the fake previously replaced RELAY and I can easily smell the burning scent of an electronic item. It was clearly blown. I went ahead and ordered the part online (currently waiting for it to come as this was written). Now me being the curious little one I went online did TONS of research on the problem and if I had broken anything else... went out got a Mulitmeter, tested some wires. Tested the connections for the relay that I blew (oddly enough, there was no power coming through the wires that connected to the old fake relay). So I got a bit scared and thought maybe something else was broken, checked the fuse it seems fine. Continued to check other things but still cannot figure out was was the REAL cause of the issue. I tried bypassing the RELAY but that didn't work. My bike feels lifeless and DEAD.

It would be a huge honor and a pleasure to get a reply from anyone... I would like to educate myself with anyones advice so I can better serve my bike. I will wait for the original RELAY to come in and see if it fixes the issue. But in the mean time I would really like for anyone to just give me an idea of what went wrong.

Thank you all again, and have a pleasant day.
Please help.

Well the relay that blew was a 4 PIN 12V 40A which is a universal autmotive relay replaced by the previous owner. The original manufactured relay is a 4 PIN 14V 30A HANDOUK relay. I am not sure if it is connected to the Starter Relay Solenoid or not because I don't know how to test if it is operating correctly.

The universal relay that blew:


The original manufactured relay:


The starter relay solenoid that you may have been referring to:

As you all know a car battery outputs a higher amounts of voltage then a bike battery when its fully charged

If its a 12v car battery then no, its a 12v system they are the "same" voltage. You mean it may have a higher amperage than a bike one? That is assuming you didnt take a 24v battery and hook it up to your 12v bike?

How charged was the car battery you used? If it wasnt charged thats probably your answer as to what happened.

*EDIT*

Just as I posted I noticed you said that car battery was not hooked up to a car (or a car thats running), yep that probably explains it.

Okay ya, so the part came in, I double checked the fuse (I realized i miss looked the fuse, so I replaced it.) Now the bike runs great.

I just ran into another issue, as the bike was sitting for a while waiting for parts I hand washed my bike using very low pressure garden hose, to clean the bike up. Now the bike has difficulty starting up, the Starter Relay clicks fine. But when I try to start it (in neutral of course) it acts as if it ALMOST has enough juice to power up, but just ends up dying. The battery checks out, it charges fine... I am hoping for it to fix itself when it dries itself. Even though I hand dried everything as well. I am very disappointed with this bike :(

Please help me with any advice :)
