Engine won't start

[art806]

Guys,
My car wouldn't start today. Bunyi klik, lampu warning kat
dashboard semua padam, spark melompat within the +ve clamps (between the
gap where we tighten the nuts) with a bit of smoke. Check the battery
terminal, fuses and everything seemed ok. It happened after I installed a
power amp. I took out the live wire for the amp from the +ve battery terminal and
the engine would start.. Just now I tried to start again, same thing
happened, a click and all warning lights went off. The +ve clamp of the battery felt warm although the engine is cool and not running. Is that a sign of short circuit?
I don't think the audio installer messed around with the wiring apart from joining the live wire for the amp directly to the +ve battery terminal. What could be the problem? BTW the battery is only 4 months old.... Thanks for any help.....

Sounds like you have a short circuit problem because you noted that everything is fine after you take out the power for the amps.

I think the "click" noise is coming form the starter motor, on my opinion, u should check on ur starter motor.

The fuses (amp, radio, starter motor, ignition) are all ok, relay, I haven't checked cos don't know how to do it. This morning the car started again but I'm waiting to see if the +ve terminal will remain warm long after the engine has cool down. I still feel the power amp has something to do with it...

After about 4 hours, the car is ok now. The engine will start but whenever I connect the power amp fuse and switched the radio on, the rpm is erratic, running between 400-800. Guess the amp is at fault then. Do you think I should do an electrical test to see if any relays are affected?
