Hoo boy! It may be that the 7 second interval is tied in with the wiper control switch. Does your Jeep have "intermittent" wiper settings? If so, one of those settings may have defective contacts that are attempting to cycle the wiper motor. Wiper motors have an "end switch" which is powered up even when the wiper control switch is turned off. The end switch is what interrupts the power to the motor when the wiper arms reach the "park position". Intermittent wiper settings exploit the end switch function to give you that option by feeding the wiper motor a momentary application of 12 volts, just long enough to move the wiper arms off of the end switch park position. The end switch circuit will then carry the wipers through one complete stroke before parking the wipers again. The various choices of intermittent stroke timing reduces the pause time between the short power applications, the end switch does the rest. You can probe the wires that connect to the wiper motor to see what sort of readings you get at different settings of wiper speed and parked. As I said above, you should have one wire that remains "hot" even when the wiper switch is off. Intermittent wipers will send the brief power pulse to the motor on the "slow speed continuous" wire. Once you identify which wire works low speed continuous, then check that wire in the intermittent positions to see if this is the "spike" you have been seeing.

Habi Regarding 2 speed pump options for your pool, there are quite a few as this technology has been around a long time. As long as you stay with a trusted brand name and have a local qualified installer that stands behind their equipment, you cant go wrong. They will size the 2 speed pump for your application. There is not much power consumption difference at low speed when comparing a 1.5HP to a 2.0HP 2 speed pump, so if in doubt, go with the bigger 2 speed and you will still be saving lots of energy over your existing 1 speed. There are no true 2.5HP 2 speeds out there. These are called up-rated pumps and are really 2 HP pumps. All the technologies mentioned in this post will work for your solar setup. The key to making low speed pumps work with solar is to momentarily prime the solar panels first with a higher speed, then the rest of the cycle can be ran at low speed providing heat, filtering and circulation for your pool saving lots of energy over a 1 speed! The variable speed pumps will save more energy over 2 speed at low speed as long as you do not run the variable speed at high speed very long. If they are ran more than a couple hours per day at high speed, then the power saved at low speed operation is erased and they will start costing more money to run than a 2 speed at high speed. If your electricity rate is high and you will not be using high speed that much, the variable speed pump may make sense but only you can justify the added cost over 2 speed. To calculate the return on investment for a variable speed pump over a 2 speed pump, use about 200-300 watts savings per hour of run time in low speed. In high speed, use about 1,000 watts cost per hour of run time over a 2 speed. Regarding DIY systems to run your meter backwards, I am not aware of any. You can google "net metering" for more info on this technology and also "using solar to run meter backwards" for some mfgs out there. There are also hybrid systems that provide heat for your home while at the same time generating electricity to feed back into the power grid to run the meter backwards and there are even generators that run on waste cooking oil that will feed power back into the grid. It is an emerging technology and is very expensive at this time for US residents. In Europe, the governments are helping promote the technology with heavy buyer incentives. The US has not reached this point yet, but its being evaluated. Hope this helps! Subl1002- If the variable speed pump is going to be used for light duty, low flow circulation for a majority of its operation time, the technology can not be beat on efficiency. Either variable speed or 2 speed will work for solar. Solar does provide some challenges for variable flow (VF) technology because the pump is trying to adjust to sudden changes in system pressures, but there are work-arounds for this also. 2 speed and discreet speed (such as 4x160 or VS) will work just fine for solar. The added up front cost for variable speed is a personal choice based on 1) return on investment knowing hours of low and high speed operation 2) value of having several different speeds instead of just 2 speeds and 3) having the latest technology no matter what the costs (some people just like to have the technology and are willing to put up with the costs and complexity). At $.095/KWH, personally, I would opt for the 2 speed either with or without solar. The return on investment will be more than 10 years for a variable speed pump over a 2 speed. But, if other factors mentioned above are important to you, the variable speed may be a better choice for you personally. Regarding reliability of the technologies, I think the jury is still out for variable speed pool pump products. They have not been on the market long enough to have much history and there are not very many of them out there compared to 2 speed and 1 speed. From my HVAC experience, having inverters in a harsh environment, such as piggybacked on pool pumps in the backyard, has not been proven reliable over time and is expensive when it comes time to replace the inverter. Hope this helps!

I guess we just have severe absent-mindedness. If I'd look for the light, or put a hand on the door, or listen carefully, or even remember that I've started the dishwasher, that'd be fine, but DH and I often have an abandoned glass in the living room, or a plate from a snack, or a small dogfood spoon from feeding the beast, or a knife from an evening piece of fruit, etc. that we want to put in the dishwasher, and when I'm talking or thinking about something else or looking out the window I just walk up and open the door. If the light were more conspicuously shining on the floor (or, ideally, integrated into the handle), it would register, but shining on the bottom of the countertop overhang makes it virtually invisible when you're right in front of the dishwasher reaching to open it. It's a minor complaint and I really like the dishwasher, but I wouldn't mind a different sort of indicator.

Okay, I fixed the choke for easy starts, but I must have messed up the diaphragm when I put the spring and cap under it instead of in the carb body. After putting it back together right, it started right up and ran great. Then, it suddenly stopped and now will only run for ten seconds at a time. Sure sounds to me like the diaphragm popped resulting in no fuel pumped. I had to go out this morning anyway so I stopped by the small engine shop and picked up another one.
