Still working on the 1977

Trillium 1300, time for some

electrical improvements. Fuse holder on my converter was stuck in place, so reluctantly, I had to encourage it out. Usually when I encourage stuff out I will hear that distinct snapping sound when something breaks.... (Encourage = prying it out). But leaving the old stuck fuse in place was not an option. Either it comes out without breaking, or I start shopping for a replacement converter.

Well I got it out, 5 amp fuse was basically melted and one end was broken off! Amazing any of the 12 V was working.

I decided to compare the stock interior

lighting load to the capacity of the converter.

Lets see, each incandescent 1141 bulb uses 18.4 watts. So then count the bulbs: 3 above the sink, 1 above the gaucho, 3 above the dinette, and 1 on the side of the closet (vertical, facing the dinette). That's 8 bulbs, for a total of 147 watts. 147 watts divided by 12 Volts = ~ 12.25 amps. The outside door

light runs off the same system, if you turn it on, thats another 18.4 watts which brings us up to 166 watts ~ 13.8 amps.

Now running all the

lights at once might be unrealistic, but very possible, Certainly running all 8 inside is very possible!

With the 5 amp fuse, my available capacity is 60 watts, quite a shortcoming. If you could find a 6 amp fuse (the rating of the converter), capacity is 72 watts. A 10 amp fuse doesn't really increase the capacity if the converter puts out 72 watts but eliminates blowing the fuse with capacity left.

Seems like a problem here: the converter's capacity of 6 amps, or 72 watts, means only four bulbs can be on at once. That means the sink

light and one more

light. Or the three dinette

lights and the single gaucho light. Don't leave the outside light on or one light will have to be off.

How/why they designed a system where they had over double the demand in

lighting versus the capacity of the converter beyond me. Maybe my math is wrong! If my math is OK, then the solution is LED

lighting. Instead of 18.4 watts per bulb, the LEDs use about 3 watts per bulb. That means you can run up to 24 bulbs at once.

So I ordered

LED lights on Amazon, including several doubles, a reading light, and a single. Two doubles will go over the sink and stove (four bulbs), one double over the gaucho (two bulbs), two doubles over the dinette (one per side, four bulbs total), a single above the rear window (one bulb) and a reading light on the vertical closet wall (one bulb). So 12 bulbs total versus a capacity of 24. I'll leave the outside light alone for now, as even if it is turned on, I'll be below the 72 watt limit.

The doubles all allow for turning on just one light or both (or none). So the additional lighting gives me the option of having more light in an area (like the dark to me gaucho with its current single bulb). And no current light over the stove at all. I'll be positioning the two doubles so one is towards the sink and one is towards the stove.
