I've been messing with serp/pulley combos the past few weeks. Yesterday, I paid the price for my serp-less recreational day-driving. Jeep stalled. Given that I have fairly precise knowledge of my driving-time & conditions, the snafu provided an accidental revelation that may be useful to somebody...
Available CRD run-time in the event that you lose charging, daytime-driving: - 1.5 Hours before "Charge Warning" light illuminates (looks like lightning-bolt, located on left-center of cluster). Aggressive-driving. - After "Charge Warning" lites, .5 Hour before stall. - Total available driving-time without serpentine/alternator= +/- 2 hours.
Obviously, your available battery-energy depends on: A. Day vs night driving, & accessory load B. The quality and state of your battery(s)
I have a healthy 5yr.old Optima 800cca 'yellow-top' battery. CRD definitely starts to "sound funny", idle crappy. However, I found that it remained rocket-smooth under heavy-throttle. Mine stalled while parked at idle for almost 1/2 hour at a "Yonke"**. My buddy was waiting in the jeep and said it was uneventful, no dramatic shaking or "death-howls", just suddenly stalled. I'm not certain how it would have finally pooped-out if underway in city-highway driving.
I have a Kennedy-pump installed. I just-now realize THAT was the main culprit that drew-down the battery! Any thoughts on how long she'd putter day-driving without an electric pump, given that the tbelt energizes the injection-pump?
* I accidentally discovered that the OEM belt will still provide temporarily-adequate tension with Idler Pulley B removed (w/stock IPA); however, it jumped & shredded next day. ** =MX junkyard, aka "Automotive Salvage Boutique" to quiche aficionados...
