Wanderlodge Question: electical problems

[GARY MINKER]

A fuse link in the charging circuit has to be a bit larger than the rated output of the alternator by about 20%. Typically a 150 amp alternator will get a link of 180 amps. If the link is in the drain side to the coach, play it by ear and figure that even with every light on, you won't draw more than 120 amps. 1-0 wire should not be used for more than 150 amps anyway so there you go. I do not see any links in the schematics for my 1985 PT-40 Gary --- On Tue, 5/26/09, freewill2008 wrote: From: freewill2008 Subject: [WanderlodgeForum] Re: Wanderlodge Question: electical problems To: WanderlodgeForum@yahoogroups.com Date: Tuesday, May 26, 2009, 1:32 AM There is a good chance that the fuse link is actually one of the ammeter shunts. A shunt could be mistaken for a fuse link. It would explain the erratic ammeter. It is important to figure out why it is burnt in either case because it takes a lot of power (think potential heat) to fry either a main fuse or a shunt. For help, try to find someone who recognizes what fried and can help find the reason why.
