Hey Mike, I got out your electrical drawing out here... Since I brought it up, I'll look it up! One side of terminal #1 to the dolphin is oarnge and the...
I saw what you mean the other day actually. But I remember a pic of someones junction box that had a pink wire in it that went to the Magnecharger hardware....
So far so good. Now try swapping the DVM leads. Try 2-1, 3-1, 3-2 as well. Of the hundreds and hundreds of fets that I've replaced, 95% fail shorted. In fact...
Looking at "204550A - ES-10A Truck Functional Block Diagram.pdf", there's a reference to a 16 PNK wire from the Ignition Sequencing Lockout which goes to the...
... That sounds odd. ... That sounds right-ish, you're seeing the 100k resistors. ... Also right-ish. Check some of my posts from awhile ago, I did a lot of ...
This is a good sign. That fet is not smoked. I think that your brown ooze just might be the conformal coating in that area looking funny. Most of what happens...
That's a good sign to have that sticker. It shows that the rework got down to that unit. It's more like upgrading than anything else. That jumper Chris refers...
... Really? I see that on newer Dolphins and not the older ones. Always the same wire as well. Why do you think it's a bad trace, and why that particular one?...
I've been through close to a couple dozen boards. That jumper when desoldered at one end, shows no continuity on the original 2 points. Some old boards don't...
That board of Ken's sure is a replacement for the precharge relay!!! I checked out the datasheets for all of the components. From what I can see of the trace...
I just passed 3000 miles since getting EV-26 back on the road. She has 15,105 on her now. I made a round trip today at lunch of 27 miles of mostly highway 65...
Hah, that reminds me, I had to enter the new pack capacity after I installed my 110 Ah batteries as my SOC dropped way too fast. However, upon entering the...
It's odd that they stopped at 100ah. Changing the ah capacity gives a real soc reading. Although as the batteries age, the ah capacity has to be lowered. Also...
I have been working on finding a digital meter solution that represents State Of Charge in an analog view, and use a digital view for voltage and current,...
It would be nifty to have nice backlit meters for sure. The 12v system and the pack have to be totally isolated from each other. Most of what you have drawn is...
It's true that it assumes it's new everyday and 75F. My 80Ah pack is roughly the same capacity as the original dual strings of 38AH Hawkers. I have cross...
Hi Mark; What is the AH rating of your pack? Or the current AH capacity? How far can you drive it? Do you know what the weight is? It's encouraging that...
Chris & Mike, Have you ever looked into recreating the main board in the Dolphin. Do you have any original schematics? I understand the minimum price could be...
Thanks Mike and Jim, That would be cool to get the in dash SOC meter working, at least for now. The meter is always PEGED to full. Maybe sombody before me...
... Honest answer from my point of view: No. While I have a lot of ability at fixing problems and such, I really don't know HOW to design a controller from...
One of our members did work on making a system with help from others and gave up as it's one huge task to develop a system. The only board schematics are the...
The trucks often come with the meter pegging over the full mark only to come down to 80% when the truck is dead. There are many posts. Somewhere, I think the...
Truck bed removed. That was a milestone. Used an engine hoist and straps. There are eight bolts holding the truck bed to the truck frame...seven same and...
The Dolphin in your truck only needs about 270 volts to boot up. Before going to all that work of removing the batteries. Try charging those 8 top batteries to...
Since you're plugging in now... When you plug in, what do you hear and what do you see? You should hear a very small click from the Dolphin, that is the...
260V on a pack that has been sitting is not so bad. The inside of the battery box looks very clean and someone did a nice job with the spacers and insulators....
