no start battery good clicking sound on firewall

Sounds like you need a starter solenoid, a new battery possibly as well.

get a NEW battery and chase the end of the 1/0 black cable with a coarse wirebrush to insure 300 cold cranking amps potential there~ everything will be okay with renewed FRESH ground~

five years old is a grandpa with the modern tin/antimony batteries...will stop accepting a charge ten percent per year....date of the first charge is noted on "knock off" labels on the top of the battery...1991 car....should have been through three batteries by now~

I need to stress test the battery. How about if I put a ten amp load on it and see how the voltage holds u;p?

Yes the headlights do not light, however the battey shows 12.7 volts with all cells showing good specific gravity, I put it on a charger which said that it was at 85 percent. Then charged it to 100. I will next check voltage between pos terminal and chassy. Thanks

....just clicking means starved of amperage...12.7 Volts may be present, but if it isn't pulling the 300 amps thru that will not help our cause...a "load test" of your battery may prove it to be okay, but the amperage ain't getting through to the startermotor....check integrity of the 1/0 cables~

how's your wirebrush doin'? sharp enough for the job at hand? go and steal your neighbors barbeque cleaning brush for a while to do the job~....oooo may not be scratchy enough....scratch that~

Thanks all, I think there is a bad connection to the ignition dashboard area cause everything looks good on the high amp circuit and the batt and starter are only a year old. So thats where I'm working now.

a hearty clamp connector (like with the welder) connecting dash to the negative ground (while already there....may have suffered from rust) to the ground may make it act normally~

was this in a drowned state at one point in time?

Did you ever find the problem? I'm dealing with this same situation.

'93 Beretta, battery charge seems good -- full lights, radio,heater functions, door buzzer full volume, no 'grinding DOWN' sound when trying to start. Found radiator water low; would that matter? Additional: after turning key back 'off' heard low-loudness mechanical noise for few seconds, like small motor still running.

My truck seems to have battery , i try to crank it up and cuts off as it has no battery . But i put the key forward and lights are on everything is on ! Any suggestions anyone ???
