Oh yea, I forgot all about the grid heater, that is typically a fairly short duration load though. @Skyhawk13205 if you are experiencing a significant voltage drop when the grid heater is engaged, I would suspect weak/dirty connections. The giveaway for this is if you measure the voltage at...

Did the documentation say anything about how much power that equalizer consumes? The meters are cool, but if they are on full time they have to consume something. And like I said above when the 12v side is loaded, like engine off headlights on, the balancer will probably be passing it’s max...

You cannot charge from the cigarette lighter or anywhere else in the cab for that matter. The diodes in the polarity box prevent this by only allowing current flow in one direction toward the cab.

The ECU and TCU load are probably not all that great. Then there is wiper, heater-A/C and I supposer air dryer heater when its cold out. And of course + any 24v lighting you have added. You would have to measure to be sure, but all up probably not more than 30A @24v. Where did you come up...

I think the membrane and ribbon are supposed to be one piece, joined where I circled in red. The ribbon then plugs onto a connector on the main board before the potting is poured… it has been so long since I dissected mine, I just don’t remember, but that is the way a membrane keypad is...

Those look similar to molex connectors. On those the male and female pins have barbs that spring outward and rest on a little lip inside their respective hole. They are removed with a piece of tubing with the same inner diameter as the smallest diameter of the hole in the connector. You push...

Yea you can shift into first anytime. Its kind if annoying when wheeling. I would like the programming to start in first when in mode so it would go from R to D1 and back with one push as those ratios are closer together. I have heard that when you select first in normal configuration(not...

Starting in 2nd is normal. 1st is really really low... Press amd hold the up and down arrows for 10.seconds. it will beep at 3 seconds indocating it cleared active codes, and again at 10 seconds indicating all codes cleared

On the A0, I think the ground is 1/4-28, and the 12 and 24 are 5/16-??(forget the pitch)...

What Berzerker said, plus a 12 or 24v maintenance charger, either plug in or solar to provide the make-up/maintenance energy. Battery balance in parallel batteries, since they are tied together, is purely a factor of internal resistance and battery chemistry. Basically one battery will be...

I think the only thing I would caution against is engaging the PTO at high RPM, and of course with the winch in or out switch engaged To make things as easy on the PTO clutch pack as possible. The winch PTO drive gear is hard coupled to the transmission so, like the scavenger pump on the...

You know the mind is a funny thing. That little exchange earlier dredged up a memory and a previous discussion I had completely forgot. The PTO drive gear is on the back end of the turbine housing, which is hard bolted to the flywheel. The rear half of that housing is the TC pump, the TC...

Dont we all...

Yea but it doesnt have to remain in neutral, there is a way around the neutral requirement in the standard installations if I recall correctly. Since you are not commanding the trans for PTO control, you are correct, it won't ever go into lockup, but a little added throttle will cause the TC...

I always start with what goes click and what dash lights are on when you turn on the ign sw? K2(ign) K11(alt excite) and K24(starter lockout) should energize, and the oil light in the dash should light. Then I ask what goes click when you push the start button? K1(starter) in the power panel...

Well like I said, that PTO light might already be wired, or mostly so…

The pto on/off sw is still in there, it is S5/6 in his first A1 drawing above CB45 which provides the winch power. he is just going to send power from that on/off sw right to the pto relay, instead of sending it to the trans, which then powers the pto relay.

I think the main reason for the transmission controller interface/approval was to limit overall load/HP thruput in the transmission, as they use allison trans pto output to do a lot of things, and it can deliver a significant amount of HP. I dont think the use of a winch will ever add enough...

Thats an A1R relay/fuse module. They use 4 of them for the power panel. They are like the transmission Vehicle Interface Module used on the A0…

For maintenance, it doesn’t have to be a fancy equalizer. A basic 2-5A unit is $25-$35. A basic maintainer/float charger, about the same. Even a small unregulated panel will work, the battery mass will regulate the output of a small panel, as it simply doesn’t have the energy to...
