i dont like these elec wp system....

when ur mechanical one fails, it leaks, and drips on ur opti and causes to u misfire etc, so u know something is going on...

when ur elec wp fails ,it over heats, and can cause alot of damage

 

$115 is cheap insurance for those of us who're not 'electronically inclined' enough to duplicate this sort of thing our own. I think this thing is a great idea.

 

The problem with that setup is when the alarm goes off, your motor is already starting to heat up. Then you have to pull over very quickly. With our system you know immediately, before the motor heats up. This way you have plenty of time to pull your car over to a safe location before the motor gets to hot. You even know what the problem is before you get put of your car. As for the easiness of the system, it only has 6 wires in it. 2 wires are for power to the system, 2 sensing wires the are spliced to the pump's power wires and 2 wires that you install in series between the pump's ground wire and ground . The power and sensing wires, LED and buzzer just plugs in to the box. It is a very simple system to install using the wiring diagrams and instructions.

 

I understand your reluctance to use an electric water pump. Many people have expressed this concern and stay away from electric water pumps because of that reason. People with those kind of concerns are the ones we developed this system for. If the pump fails then you know immediately. This system gives you peace of mind when running an electric water pump.

 

yeah, thats true... i just didnt know such thing existed...

but the elec wps do fail more then mech water pumps

 

I've never heard of a system like that for electric water pumps, but it's quite unnecessary. Monitoring the pumps current and voltage is the best way to monitor the motors operation. If the pump seizes, then it will draw excessive current and blow the fuse, giving you a loss of power warning. However the most common problem with electric water pumps is an internal electrical failure of the motor from an open circuit. Usually from burnt winding, broken wires, etc. When this happens the pump will stop drawing current. No other system on the market can give you a warning of this.

 

Does the system give any indication of over current? This would seem to be the most common indication of failure for any electric motor. If it can detect any abnormalities in current draw then it may be worthwhile but most of the problems I have seen actually have to do with faulty wiring or relay problems. The diagram from the AKM site is cheap insurance for a simple relay or wiring fault.

 

Very true. There has always been a compromise when running electric water pumps. This system was developed to reduce those compromises.

 

You couldn't monitor current abnormalities very well of an electric water pump because there are so many things that could affect the amount of current draw. Things like the water temp, electric motor temp, the amount of flow in the cooling system (from things such as an open or closed thermostat, the size of opening on the thermostat) and start up current draw could effect the load on the impeller. The more load the more current draw. The current draw is just to dynamic to monitor abnormalities. Just illustrate this dynamic value, the pumps normally draw 5 to 6 amps during operation under "ideal" conditions, but yet CSI and Mez still recommend that use a 15 amp fuse on the pump. Because of this our system only monitors whether the pump is drawing current or not. I havent seen to many problems with faulty wiring on electric water pumps. As long as you follow the instructions, it will work properly. Most failures I've seen have been from internal pump failures. Very rarely have I seen a properly sized fuse blow.

 

Mine does all the same with one light and cost about $20. It's all in the wiring. When the light is off, I have either no ground, no connection to the pump, or no power.

I know it does. But it does not warn you of an internal pump failure. Like I said, the system was primarily designed to be a current monitor. No other system on the market will do what our system does. All the other LED or warning light tricks do not monitor current.

 

Autometer makes a prolite and sensor for the H2O temp that costs about 60$ all together. It looks fairly neat and will tell you when the coolant temp gets too high. They have sensors for the oil pressure also. Oil light saved me an engine once.!!

 

I can tell you warning light or not if the pump stops you better shut the thing off and not try to drive it to the next rest stop. when I first installed my CSI pump it took about two minuits to rocket the temp over 225 deg from 180 when I acedently pulled the W/P fuse rather then the fan fuse I was mesing around with at the time.

 

Sure glad I'm one of those electronically inclined... $20 in parts is pretty low actually.. I'll probably spend about $40 to accomplish the same thing; just a PIC chip with a Voltage/Current/Ground/Open Loop detection circuitry...

From a selling standpoint, I'd estimate that ~$100 is a fair price for that piece of equipment.

But for me, I'll just incorporate it into my PIC controlled LCD data display

 

I have an led setup too with 2 lights. One shows no power, and 1 shows no ground. Either way, the pump isn't working and one of the lights will come on. I made the circuit having little electrical experience and managed to fit 3 leds(one for nitrous) and 2 micro switches in a bracket no bigger than 1"x2" which is nearly invisible in its location. I would like to add an alarm. Where can I get one?

Can that auto lite meter be set for different temps?
