We have two cristec 60 battery chargers on out JEANNEAU 53. After installing a new genset, we noticed one charger works but the other does not. Confirmed power is going to the unit and our next step is to check the input ceramic fuses. Anyone have similar experience?

My Cristec charger on my 2007 SO39i started charging erratically so I replaced it with ProMariner which I am very happy with.

I have a 30 a Cristec loader in my Jeanneau. An internal fuse was melted, as well as the fuseholder. Easy to replace both.

My Crisrec charger died three years ago and I replaced it with a KISE smart charger that can handle three battery banks. It has worked very well for me, and I have the 60 amp model with four Trojan AGMs. The four batteries are group 31s, 100 AH each. Cost was $499 US for the charger.

I have got the same problem with my Cristec CPS3. All the fuses are OK, 220V loaded, but there is no any output voltage and indicators lights off. Does anybody fix this fault?

Worth contacting the factory, esp if in Europe. They sorted out an issue very quickly for me a few years ago and speak English, if your French is limited. www.cristec.fr/english/ |

Measure first of all if 220 V AC is coming in, before the fuse and after it. If yes, is there coming appr. 15 volt out of the DC rectifier. If not, the rectifier is damaged. That is what happens mostly. Check than the diodes and condensators of the rectifier. That's the easy part, if this works it becomes more complicated and if you are not an electronic engineer it will be difficult to find the reason. In the Netherlands there are Repair Café's where they repair free of charge. May be there is one in your country. See repaircafe.org/en/ |

Thank you for quick reply mates! Yes, there is 220V before and after ceramic fuses. Because I did not find any reset button on the charger block I`m going to take off boat charger unit to test that DC rectifier for faulty diode bridge and capacitors. I will inform you about the progress of this common problem of CSP3 repair.

Hi,
When we returned to our boat this year we switched on the battery charger on the main switch board, within a few hours a bad smell developed, we discovered two of our five AGM's had cooked.They were isolated by an electrician, which left us with three connected. We have monitored our system and found the outer case of our Cristec CPS3 charger to be getting hot. My question is "can any one tell me how hot/warm theirs is getting ?" Ours when on boost ours gets very hot, switch off SW1 and the case cools to warm.
Also it recommends in my manual to get the charger inspected every 5 years by a Cristec approved engineer. Has any one had this done? if so, were there any problems?

I share your frustration as my Cristec charger stayed in boost mode toasting 4 of my 7 batteries last summer. I did
discuss this and a posting in these pages previously. I had no trust for the Cristec charger after this episode and it was replaced. There have been other postings on this charger and a recommendation is to disable, turn off, the boost function
on the charger.

My Cristec also died last year and after hearing dubious reports decided to replace with Victron which I've had before. Superb products.

Hi Mike, good to see you back on the boat after your big trip.
A bit sad about the batteries, sounds like a new charger is in order, cooking batteries gets expensive as well as annoying. Turning off the boost is only a “get you home” solution until you can get a new charger as it means you don’t quite get the batteries fully charged. But it should save cooking more batteries in the short term.
Ours in not a Cristec. While it gets warm, I would not call it hot, but obviously very subjective terms. I have not tried to measure the temperature. Next time I am on the boat I will get out the infrared thermometer, always good for quick comparative readings. I would prefer to see it a little cooler, but I have always put the warmth down to minimal ventilation in the charger compartment. Not easy to increase the air flow around there.
Might be worth following up Malcolm’s suggestion earlier in this thread (17 Dec 2017) to see if there is an “approved engineer” in your area, to see if it can be repaired.
