Very weird voltage drop problem
I have a Sony amp + Stinger 1 Farad cap. powering one JLW6. Recently I am
having some weird problem.. in some day, when I started the amp (not even play music yet) the amp. didn't start (the amp. internal protector kicked in)!! So, I put a voltmeter between the +ve and -ve on the amp. Surprisingly, the reading is around 7 v!!! Then, I put the voltmeter +ve on the fuse (see photo), and -ve to the body of the car, it read 12V and then all of a sudden everything worked fine.. the amp reading was back to 12V ??!!! That really annoyed me... Any of you expert experienced such odd problem before? Originally I thought it was my old cap problem, then I replaced with this 1 Farad cap (brand new in photo). Still got the problem in some bad days. Not every day though... in some good days, the whole system worked perfectly.. weird.. See photo he http://members.rogers.com/londonboy/images/amp/amp.jpg Thanks for any advice... |

Replace your fuse, they sometimes go bad at the connection and will do what
your is doing. Paul Vina "John Addington" wrote in message . rogers.com... I have a Sony amp + Stinger 1 Farad cap. powering one JLW6.

Very weird voltage drop problem
Oh... you have seen this before.. I am glad that I am not alone. Maybe I
will try to replace the fuse, do you know what is the best chemical to clean the connection point? WD-40?? Thanks again.. "Paul Vina" wrote in message news:ai2fb.664743$Ho3.137661@sccrnsc03...

It's not the connection point exactly, it's the solder joint inside the
fuse. Replacing it is the only way to fix it. Paul Vina "John Addington" wrote in message le.rogers.com... Oh... you have seen this before.. I am glad that I am not alone.

Very weird voltage drop problem
I can attest to this... I had a 4 ga cable running through a vehicle and
the same problem... A friend suggested changing the fuse, I thought the fure is good, that will never help... It helped... I have also seen the bad ground thing.. Cold solder joints or just bad connection between groundwire and body. "Paul Vina" wrote in message news:0y4fb.663277$YN5.511115@sccrnsc01...
