Start problems

[Roberto]

Hi , I would like some help with my truck 720 Z That I tried to start this morning and was no response on the panel o starter I check the battery and was ok, I check the conection and were ok , so I decided to get my battery charger and give more power to the battery unfortunely the result was the same , I left the charger like 10 minutes and try one more time , and nothing I look around the ignition switch and open the key no power at all , I continue moving the cables and suddenly I got light on the panel but a intermittent clicking noise under the passenger side was present this time and let the starter turn but just a little bit the confuse situation is that when I turn the signal or any other instrument the noise under the passenger side increase a lot and even with the charger don't start . Did some one have any idea what is the problem , the battery is new. Alternator is new if helps I check all the fuses and are 100 % ok .... I assume that it has to be with the noise under the passenger side .

It is the battery cables. Clean them and the battery terminals.

do you have voltmeter ?

 

Volts at battery?

[banzai510(hainz)]

to ck cables or corrossion at the cables

 

get a volt meter and measure from the center on the battery post then to the battery cable lug. if you get like 2volt or more difference with KEY ON then most likely the cable end is bad or dirty contacks.

Ck both cables.

 

if good it will read zero.

Or, just clean them. Takes like 5 minutes and should be done once a year in any case

P.S. A battery charger will not start an engine unless it has an 80 or 75 amp "Start" setting just for that purpose.
