Trecked Posted February 20, 2023 Share Posted February 20, 2023 (edited) 2009 Bajaj Pulsar/Rouser 200. Took it in for an idle/start issue. In their diagnosis, mechanic bypassed the fuses (fuse box with 2 tube fuses) and directly connected the wires (for reasons that are beyond me) along with jumping the starter relay with a screw driver numerous times. I noticed when I came back after going to the store for a few minutes. Went to start the bike and the dashboard wouldn’t come on. Bringing it up to him he seemed surprised and didn’t know why. After over 30 mins of fiddling around with the wires trying to figure out why, we take out the panel and noticed the PCB (the electrical board) was burnt. He casually says “Ah, here is the problem” as if it spontaneously happened by itself. Did it? I would now like to know if deleting the fuses coupled with jumping the starter relay AND connecting another battery to the battery already in the bike could have causes the instrument panel/speedometer to fry. Appreciate your expertise in this folks! Edited February 20, 2023 by Trecked Quote Link to comment Share on other sites More sharing options...
Mississippi Bullfrog Posted February 20, 2023 Share Posted February 20, 2023 I would have thought that to be a strong possibility. Bypassing fuses is asking for trouble. As for connecting a secondary battery, it depends how it was connected. In parallel or in series. If it was in series then you're getting 24v into the system.

Battery on the bike didn’t have enough juice to start it so he got another battery and made the terminals…ummm…kiss? Quote Link to comment Share on other sites More sharing options...

In series the voltage will increase as you add batteries ie 2 X 12v gives you 24v 3 gives you 36, you do that by connecting the earth from one to the posative on the other, you can't achieve this with jump leads simply clipped ont an existing battery, so it's unlikely you got 24v, if its jumped from a running car you can force to high a voltage onto the bike and cause damage. Fuse will depend on what it's protecting, a fuse is rated to go so as to protect circuits from suffering damage in the event of a failure.
