My other car is a 2008 honda odyssey exl res. Unlike most vans its made to handle 4 disabled people in wheelchairs. I currently have the front seats installed, but no second row. Its my mothers car and driven on the weekends. I have learned to plug in the trickle charger 2 days before it needs to be driven for it all to work. The van only needs 9 volts to start and run, but the wheelchair computer and parts needs 12.
The alt and everything is fine except the bat is always short or needs charging. At first the van just works, but after driving it some the wheelchair stuff comes to life.
So, been thinking that a bigger battery isnt the solution, but maybe a smaller one that can be recharged faster? Ive been told when amp need exceeds supply voltage does down. When amps are restored voltage goes back up.
So, if I exchange the group 34 battery I have for an odyssey, XS audio agm bat or even a bat cap it will charge up in no time and I will have the voltage for the disability stuff. I got a 200 amp alt and its working ok.
Plan B was to use a large solar trickle charge of at least 100 watts with controller. Plan C is to mount s trailer hitch, cargo tray, gas powered generator with a large 50 amp battery charger/starter/jumper dealie so I can throw more power at the situation. Plan D was to use a second bat and isolator, but its suspected the wheelchair stuff is what lowers the charge til its too low to function. This kind of defeats the ability of a disabled person to be independent unless they move to a remote starter and use a circuit off that to trigger the mechanical isolator to power up the disability stuff from the second battery.
Yeah, life sucks.....
