Big thanks to Dudical26 from Aquamist...

Without prompting, Dudical offed his own free time to help a fellow EVOM member to track down the fault of a problem HFS-5 install. I believe the system is now in full working order. Full details of the nature of problem may be reviewed on the following thread if the user wishes to disclose it.

More Problems with my HFS-5

I cannot thank Dudical26 enough for taking the matter to task. He has managed to bring the system to working order in a coupler of hours yesterday, compared to my effort for weeks to no avail.

was expecting to read a reply from dudical on what he found the problem was

sure he'll add it later.
big up dudical

Way to go dudical26

. Also curious what the problem was.

hey guys -

This weekend I got together with Import Junky to take a look at his HFS-5. He had been working with Richard to try to solve the problem but things can be a bit tricky when Richard is so far away. Anyone who has dealt with Richard knows how incredibly far out of his way he will go to help Aquamist customers. Having personally been helped many times by Richard I thought I could start to repay the favor by helping other Aquamist users.

Import Junky arrived with all of the wires ran, but not connected, for the new components that Richard sent him. I began wiring everything up testing things along the way. First we checked that the HSV worked by supplying 12v via a power supply, everything worked. Continued wiring up the rest of the system until everything was connected. As a note for everyone ALWAYS BE SURE TO INSTALL AN INLINE FUSE for the power supply to the DDS3. I then decided to test the system before connecting any of the extra components like the failsafe solenoid. The kit worked as expected so we took it for a drive around the block, again the kit triggered as expected.

We then connected the MAC valve used as a failsafe. Went for another test drive….hmmm not working. This systematic process of testing things along the way before connecting everything enabled us to know that something to do with the MAC valve was causing the problems. Starting looking over the system and we find that the fuse for the DDS3 was blown. This meant that the MAC valve was drawing too much power for the kit to handle. The only reasons this could be is either no resistor or a short in the MAC valve or wires. There was no inline resistor installed but I was skeptical this would have really blown the fuse. Pulled out the multimeter and checked for a short in the MAC valve wires….problem found. There was a short in the wires which was what blew two of Import Junky’s previous DDS3 kits.

By replacing these wires the problems will be eliminated.

Overall lessons learned that everyone should follow –

- Always install an inline fuse for the power supply; it protects the DDS3 from damage in many situations.

- If you have to run any wires either use multi-core cable with a protective shroud or run the wires through some sort of cable loom or sheath. Otherwise there is danger they will get snagged along the firewall and may get stripped and short out.

- Before connecting any external loads to the DDS3 check for a short and also check resistance. A multi-meter is worth its weight in gold when it comes to this kind of stuff.

- When installing and troubleshooting and Aquamist kit, do things one step at a time. Connect the bare minimum of wires needed for the kit to turn on. Then connect the next ground of wires, then the next, then the next, etc… By following this process you can quickly track down what component is causing the problems.

- Finally be neat and organized, it makes working on the kit in the future much easier.

I am not surprised by Dudical26 behavior, he is a great guy!
Wish to be his neighbor sometime ;-)

awesome write up dudical

dudical is the man!

Great to hear Dudical!!! Glad to know its in good working order.

Richard L · Nov 17, 2008, 01:05 PM

Without out Duducal's help. I would still be struggling with Imoported Junky for months to come.

I never suspected the lack of FUSE link. I just get the message "the replacemen board doesn't work". By the time I tried to help, it was already too late.

Import Junky · Nov 19, 2008, 07:24 AM

Well, I feel like an ass for not posting sooner. I just have so much going on. My whole house is basically being remodeled and I have a baby on the way.

So anyways, I want to give a BIG THANKS to Dudical26. He was great to work with and very knowledgable. He definately has a very systematic approach to troubleshooting. I can't tell you how happy I was to finally figure out the problem. I feel like such an idiot after seeing such a simple fault. Obviously my biggest mistake was the lack of an Inline Fuse on the power supply. Atleast now I know this system really well. I should have much better luck troubleshooting in the future if I have any problems.

As for Richard L, I can't thank you enough. For a Vendor to help a guy that bought used parts from another member is just unheard of. I still can't believe the time and effort you put in as well not including the the parts you sent me several times. By the way, I still have to send you my other Gauge and DDS3. I kept to just in case Dudical26 needed it.

I haven't done anything with the MAC Valve wiring yet. I'm working on modifying my ROM with the MAP Sensor mod and the Ecu controlled boost mod. Obviously I'll be using the MAC Valve for boost control which will be connected via the stock boost control solenoid connector. Thanks again for everyone that helped including Evan from VividRacing. Hopefully I'll have some results with this setup soon.

Mad Props Dudical26

I remember my kit didn't have the in line fuse so I rounded that stuff up locally, I'm sure I talked about it in my install thread. Best thing to do for anyone who is purchasing a kit is to go over everything & instructions to make sure nothing is missing and if your doing the install and come to a point where something is missing don't do any further work until whatever it is acquired

I'm still using the MBC and the Mac Valve for failsafe but you've got a few options

I've still got the ecu map switching harness I got from Jack of Trades I've never hooked up, maybe one day when I go to ecu controlled boost

Dubical is a great guy, helped me out with some basic stuff, and also pointed me in the right direccion many times...

BTW: just out of curiosity, my HFS1 came with the fuse to hook up to teh wire, does the HFS5 come with it? i know Importjunkie bought his kit used...

The HFS-5 does come with the fuse in the kit. Import's must still be with the old owner of the kit.

I tried to source a similar fuse holder so that I would have an extra just incase but I couldn't find anything as nice as what Richard uses. He really must spend a lot of time testing out little parts like this to find the best stuff out there.
