RE: batteries in parrallel using a bus bar

Electrically you'll find very little difference between buss bars and cables of equal size. But if bars will make it easier to service the batteries, I'd go with the bars.

RE: Electric Question...

If one leg of the 50 amp service is cutting out, it means there's an open circuit somewhere between the coach and the transformer feeding the circuit. It's a bad thing at best! Make sure it isn't a bad connection on your equipment. Something will show signs of burning.
I wouldn't plug my MH into a service that I know has that issue.

RE: How to tell tire age??

The date code (usually only on one side of the tire) will be a four digit number near the bead, 1503 means the 15th week of 03.

RE: Favorite Smoking Wood...

To me, it depends on what food I'm smoking. For example, hickory is good with beef, but not so good with halibut. I use a lot of alder for fish, and birch for moose and beef. They are both local woods.

RE: #101 needed for use of engine block heater, please??

My block heater is factory wired with a switch by the bed that can be turned on before I get up. If the temp. gets below about 40F the block heater is required. apparently I have a thermostat that won't allow cranking in cold temps. And when I start without heater in a borderline situation, the engine will make a lot of black smoke. (my engine doesn't have glow plugs).
At 30 degrees, it takes maybe 15 - 20 minutes.

RE: DC problems

It sounds like your house battery disconnect is open, or bad connection in that circuit.
BTW, a deep cycle battery for engine starting isn't the best choice. It doesn't have the same cold cranking capacity.

RE: Home Emergency Generator Question

I'm only guessing, but I think almost any electric start generator could be rigged for remote start. I've never done it, but I'd bet I could. Talk to an electrician.

RE: Electronics and the far north

Hook, Dave or others,
Do any of you have experience with GPS topo maps in Alaska? Especially for the hand held units. I have one of the Delorme topo paper atlas books but would like to have something workable for off road hiking and fishing for navigation to find my truck afterwords. LOL I have some friends that live out on the East End Rd in Homer and have found some the roads (?) they live on don't show up on any of my GPS programs. Thinking perhaps a topo map might show their street/trail/path, etc. Does any company make preloaded SD chips with Alaska as a topo map, that could just be plugged into my Garmin? I can only find the CD version listed on the Garmin web site.
thanks,
I have Garmin's topo maps of the Western US and Alaska, and they work great! Though your friend's road off East End road may or may not be included, depending on when it was built. I don't know how much lag there is. Check it out on Google Earth.

RE: Electronics and the far north

As far as the GPS is concerned, it works great here, it will take you within a few feet of a given set of coordinates every time, but the mapping software doesn't always match the real world. For example, there's an area along the Turnagin arm where my GPS says I'm driving in the water, and I'm off route (there's only one road). I found the same problem in South Carolina. Google Earth will show the same error.
Satellite radio won't work here, the satellites are too low in the sky.

RE: Why do tires have a reduced capacity whe used as duals?

A single tire may to have to support most of the load at times on an uneven surface. Take for example a rutted road.

RE: Rotisserie Cooking

I use a meat thermometer. It will depend on how hot your grill cooks, and on my Weber I have to turn the center burner off. There are enough variables on the grill that the thermometer is the only sure way.

RE: What is "low Frequency"

So what I'm reading here is that my progressive surge guard is at fault.
it may see a power blink as a change in frequency, but my guess is that you don't really have a frequency issue.

RE: What is "low Frequency"

high voltage power grid transmission lines between , power plants are synchronised
all kinds of problems can exist after the power reaches the local public utility that has the job of voltage reduction, phase shifting / reduction and distribution to the public
buck boost auto transformers fail, windings burn, etc..
so what you receive at the 240 single phase residential, can vary during periods of heavy stress, or equipment failures
The frequency of the power at your house is in sync with with the generator hundreds of miles away. Voltage can fluctuate, and phase angle between voltage and current can change, but (with the exception of the newer inverter type portable generators) the speed of the generator controls the frequency. when the speed of the generator slows, it's because it can't handle the load, and the only way it can keep running is to shed load.
Transformers and regulators (buck/boost) can shift phase angle and change voltage, but do not change frequency.

RE: What is "low Frequency"

To the naysayers: It's possible to be on an island at times. Particularly if you have a small nearby generator and the system is disturbed.
This happens in rural areas with small hydro in the area. Storms take out the transmission system, and the local plant picks up the load. Many rural substations have no frequency relays and won't trip. (Some only have fuses!)
If the OP was islanded on a small single generator, he didn't mention it. I've done work in a lot of small plants, and they all had either frequency or speed protection (they do the same thing).

RE: What is "low Frequency"

The power company relay's will be set to trip circuit's off line long before you could measure even 1/2 cycle low! (59.5 Hz). The 49-51 Hz mentioned above means that all of the generation on the system and their protective relays have failed. And you can expect the lights to be out for awhile.
You may have been able to see numbers like that just before the East coast went black some years ago.

RE: how do you know if your inverter is shot?

It isn't working when you know you have 12 volts in and nothing out. That hasn't necessarily proved it's shot yet. Check for a blown fuse, tripped overload or a loose connection. When you remove the cover, it could be obvious.

RE: suck Nocold

Under your situation, I wouldn't worry about the warranty, I'd just fix it! It would be less hassle and cost you less $$.
