Very Interesting Readings !!
Listen to this..
I had a brain wave and finally thought of something. I took my volt meter and went out to my car. Turned it on and thouched the battery leads.
12.57 Volts .. not bad
Then I Started the engine, touched the battery terminals
18.77 Volts .. woah!
So I stopped the engine and went and checked the battery again and :
16.35 Volts .. and I kept the contacts on and watched the number descend...
I think overcharging may the correct diagnosis.
I looked down past the exhaust manifod and saw the alternator easliy but getting to it....It looks as though from the bottom qould be better if I removed the panel covering the bottom of the engine.
Am I on the right track? It feels right.
