I think I killed my motorcycle battery

I had only replaced the battery on my Pulsar 200NS motorcycle 3 months ago – just before I took it on a 2-month tour around SE Asia. My previous battery was about 2 years old and I didn’t want to risk a bad battery on the trip.

But shortly after returning to Singapore, and while performing maintenance on the bike, I had absent-mindedly left the key in the ignition and in the ON position. That severely drained the battery and was left with less than 5V. After an eventful jumpstart, stalling the engine down the road, and a good samaritan assisting in “push starting” my bike using his own motorcycle and his leg, I managed to get to KL and back without incident.

After the incident, I was Continue reading “I think I killed my motorcycle battery”

Automotive fused relay quality issues

If you’ve read my previous post on my extra wiring, I’ve introduced an automotive fused relay to my 200NS. This relay controls power to my auxiliary devices such as LED fogs, USB power, and remote alarm signal.

LED Fog lights install on my Pulsar 200NS

Long weekend project…. Got a pair of these LED fog lights for my bike and a handlebar on-off light switch. Was figuring out where to put the light switch as my handlebar has no more space… So ended up installing the switch on the engine crash bar instead – just beside the LED fog light.

For those who may be technically interested, the LED fog has 3 modes – high, low, and flashing. Draws 850mA on high, about 250mA on low, and approximately 480mA on flashing mode. So my 5A fuse provision for this is definitely way more than enough.

Wiring up for power on the Pulsar 200NS

Had previously installed my bikecam and USB power port at a bike shop. What the mechanic did was to hard wire the bikecam and USB outlet to a “Ignition ON” wire on the bike. No fuse. When I asked him what if one of these cheapo made-in-China stuff short circuits? He told me that the main fuse will blow lor.

I never liked the idea of blowing the vehicle’s fuse with these “add-on” stuff. Because, the quality of these stuff are sometimes questionable, and blowing the fuse will leave you stranded.

I’d much rather have a separate circuit with its own fuse to support these aftermarket electronic add ons. So, I headed to the drawing board and came up with this…

200NS 12V Wiring Plan

Edit: Subsequently repalced the 30A fuse with a 10A, and the 20A fuse with a 5A one instead.
