Generator charging question

[GARY MINKER]

A properly operating diode isolator should have a voltage drop across it of between .45 and .8 volts. typically .5 to .75 volts. Just measure across the isolator to see the drop per segment. Any good hand held voltmeter referenced to the chassis works for down the line voltage readings. In an older or dirty vehicle, bad connections at high amperage draw is a typical culprit to charging problems barring bad batteries. --- On Sun, 12/14/08, sfedeli3 <sfedeli3@...> wrote: From: sfedeli3 <sfedeli3@...> Subject: [WanderlodgeForum] Re: Generator charging question To: WanderlodgeForum@yahoogroups.com Date: Sunday, December 14, 2008, 5:42 PM Gary, If you are coming to Q- we can troubleshoot the charging circuit there. I replaced the *&%$#*% diode with a "battery link ACR" from blue sea systems. All has been right with the world since then! Just pull the diode or isolator out and put this little puppy in its place. No voltage drop and adjustable make/break settings- Life is good!
