[Coach battery not charging]

I just did this today.

On my 88 Dolphin, the isolator relay in on the drivers side firewall.

Theres also a fuse on the drivers side fender (lower right of the photo)

and another fuse (2 fuses, one for the battery feed and one for the cigarette lighter) on the coach battery box. (you need to lift the cushions and the seat bottom to get to these.

Before you start checking fuses, I'd take a voltmeter and measure the voltage at the coach battery.

Measure it with the engine running (13.5 - 14.5 volts), and also without the engine running.(12.8 13.5)

(If you can plug in AC, also measure it with the AC plugged in and the engine NOT running (13.5- 14.5)

You may find that your coach battery simply wont hold a charge. The voltage readings will tell you this.

Hi waiter, I'm having a similar issue as op and think its my circuit breaker (as seen in second picture). I'm trying to replace, but am unsure what cord to put on what side. Should the cord coming from the solenoid connect to the battery side or the alt side?

['90 Dolphin - can't find fuse or breaker]

I am a new motorhome owner and am having an incredibly frustrating issue. I was plugged in at a camp ground and, after turning on a microwave, lost all power. I have tested and am getting power from the extension cord, but nothing will turn on. I am guessing that its a breaker or fuse, but I can't find the fuse box anywhere! Does anyone know where I should look? I have a 1990 dolphin toyota.
