Unhappy Sudden electrical system failure in my Pulsar 180 UG3

Today morning on my way to work, the digital speedo of my 6 years old 180 UG3 went blank. Horn, indicator, head lamp, tail lamp stopped working.Only the tacho was working. Intermittently the place where the cumulative ODO count is displayed started displaying 'CDI' . After sometime everything became normal and all the electricals started working fine as if nothing has happened . After some time the same problem repeated but this time the tacho was stuck at 6K RPM. Since the engine was working fine, did not dare to switch off even at signals. After reaching office saw that the speedo was stuck at 2K RPM. None of the electricals working. But Kick start worked fine and the engine started.

Any idea what went wrong? Battery is changed 1 year ago and is in a good shape. Will take it to my local mechanic but want to know where to trouble shoot the problem? Please help

Looks like a problematic battery or a blown fuse. Many symptoms that you stated were noted in my Honda too when the battery died. Worse, I don't have a kick starter in my bike, hence changed the battery same day and all the problems were sorted out.
I think it should be a good idea to check the battery and then the main fuse.

What's UG3?

The wiring harness might be damaged somewhere. If there's a place that checks wiring harnesses (like Ramkoti for Hyderabad), take the bike there. It'd be a 10-15min job for them to find the fault and fix. My old bike started to turn off randomly and the fuel meter would jump like mad for no reason. Took it to Ramkoti and fixed for Rs.120 in 10min flat.

UG3 is the model name as per naming convention for various upgrades on pulsar. This is the one with all black alloys and the headlamp fairing. The later ones are UG4(with tyre, suspension, full DC electricals etc borrowed from P200) and the current one now is UG4.5.

Looks like a problem with the fuse hidden under the seat. Even I faced the same problem a year ago. Took the bike to the local mechanic and he cleaned the fuse which was hidden under the seat. In my case RPM got stuck at the maximum.

Hi All,

I own a P180 UG4.5 bought in Aug '12 and done 13.5k kms. My bike was lying idle since 10 days(I gave it a wash a few days ago). Last night I took it out for a short errand and thumb-started as usual and switched on the parking lights. She readily started but I noticed that the trip meter had reset itself. Then suddenly the speedo display lights(including telltales) went off even though the headlight was functioning properly. It was dark and before I could confirm if the screen was blank too, it was back to normal with out me doing anything. Again I confirmed that both my trip meters were reset. I went ahead with my errand of half a km and the bike was her usual self all throughout, the tripmeter was clocking the negligible distance too and there was no starting trouble.


Now my question is:
Was this due to a similar fuse problem?
Or is it a weak battery? I have never faced starting trouble even after leaving the bike idle for 15 days in winters. Weak battery shouldn't have sustained there IMO.

Went to my local mechanic. The fuse was blown. So he installed the spare fuse and that also blew immediately as soon as the ignition was switched on. Also there was sparks coming when the two terminals of the fuse socket were connected directly. He concluded that there is a ground which is happening somewhere in the wiring and needs time to trouble shoot. Have left it at the garage. Will see what happens. :(
